Great! except for Audyssey Calibration
348763
I am a long time Onyko AV receiver fan, having used these for the last ten years.  When it was time to upgrade my TX-SR804, I picked the TX-NR709, because I have a TX-NR708 in use in another room and really like it's performance.  However, although the two receivers are almost clones, Onyko made some changes in the calibration firmware that actually degrades performance, rather than improving it.  Even with the latest firmware the Audyssey calibration boosts the surround channels much higher in gain.  The only way I can get things to sound normal is to reset the TX-NR709 to the factory default and to manually calibrate the speakers.  I first thought it might be the fault of the setup microphone so I tried the setup mike from my TX-NR708.  Same Problem!  I called Onyko tech support to find out if others reported a similar problem.  Not to their knowledge.  Hopefully the NJ tech support people will report this to Onyko engineering for possible firmware correction.

I tested this system with my Nikon SB-910, two SB-800's and two Phottix Mitros for Nikon. The TX controller is a thing of joy as compared to either my SU-800 or my previous PocketWizard TT1/TT5 setup. the YN system was flawless in manual mode for all the flashes mentioned but strangely the SB-910 would not function in TTL mode. It just would not fire. I worked with Yongnuo support in China and they finally just said I should return the unit, something is wrong. They claim their D800+SB-910+YN622N/TX works fine. Mine doesn't. So I returned the units.
I wish the system worked fully. The triggers are pretty well made and for this price, unbeatable. But I do use TTL flash and camera manual and not being able to use my SB-910 bothers me. Support is claimed but not there and the answer of "return them" from support didn't sit so well with me. Whats wrong with fixing it? I'll be investing in a Phottix Odin system next. Its more money than the YN's, said to be reliable and still less than the PW Flex TT1/TT5 triggers which were too quirky in their reliability. Overall, I'm sad the YN system didn't work as advertised. I really like the form factor and ease of use.

This is the 3rd one of these devices I've purchased.  They all have worked faultlessly and are pretty accurate.  The barometer forecast can be slightly off once in a while, but most times is fairly accurate.  I love being able to see the highs and lows WITHOUT having to push some button!  The only drawback would be that the screen has a pretty narrow field of vision for clarity.  The unit cannot be any higher than just below eye level or the screen display washes out.  This needs to be corrected to make it a five star product.

Overall I'm pretty pleased with this watch.  The clock face is big and easy to read during the day or at night.  The back-light is great.  I initially bought it for the back-light and Tide clock, but after I got it I found that you can't set your watch by the tides.  They vary in the times between high and low tide so it's kind of useless to me.  The temp gauge is also silly as other reviews have put it as your body temp interferes with the reading.  The compass I thought was pretty cool.  One thing I don't like is that you have to reset the date "day" on short months, or it will count 31 days each month.  It also don't display the day of the week witch I have greatly relied on past watches for.  So, if they put the day of the week, fixed the "day" date, removed the temp and replaced it with something else, This would be the perfect watch.

This webcam is great, except for the software (on both Mac and Windows). The settings that you can configure (exposure, whitebalance, zoom, etc) do not persist if you unplug the camera. This is super annoying if you shutdown your computer every night, or move the camera between computers. The default "auto" setting for white balance is all the way cool, so the image is completely blue. Having to reset this every single day when I use the webcam is a huge bummer.

When the settings are set, the video and audio quality are excellent. Autofocus is snappy, and you don't get any feedback from the microphone. If Logitech could fix the software / firmware to persist the settings or at least make auto-whitebalance work, this would be a 5 start product.

I had a great Heath Zenith sensor, but when I had to replace it the new HZ unit had almost no sensitivity.  Looking around I found this, and I have mixed results with it.  My sensor is a good 20' up above the garage and needs to detect motion up to 50' away.  The original HZ unit did that no problem.  This unit is good to about 30-35'  It is also more difficult to trigger- perhaps its detection pattern is not so fine grained.  It does work enough to keep but if I find a better one I'll replace it.  There are some very good ideas here.  The adjustment between 24 hours and "dark" is cool, but when cranked all the way over to "dark" it actually triggers while there is still quite a bit of light out.  Not a fatal flaw, but a bit surprising given all the trouble to make this flexible and adjustable.  The adjustment for timeout could have some spots marked for popular time periods, like 1 minute and 5 minutes; it takes a while to hunt around and find the right spot.  The "test" mode during the first 5 minutes is cool but only tests sensitivity, not timeout- a bit of a nuisance.
It is overall usable, but given how high end it appeared that they were trying to be with this product, it could certainly be better.

As noted in previous reviews, the speakers are crap. But the screen is glorious. I set it to sRGB, color calibrated it with my ColorMunki. Besides the brightness being WAY too high (~346 cd/m2), the colors out of the box were extremely close to post-calibration.  The OSD does have a 6-axis saturation and color meter as well for that fine tuning.

I'm using this as a business monitor and it's very nice.

This could end up being a 5-star product IF I can get some of the idiosyncrasies ironed out.

First off: it installed and fired up beautifully, no problems at all. The wires are all ISO color-coded, and I made no mistakes connecting everything (Huzzah!). All of the applications worked right first time - - radio, GPS, Bluetooth hands-free, etc. Oh and BTW, the GPS is amazing at signal acquisition. I'm used to Garmin taking a while to get a position, especially after sitting un-powered for some days. But this unit found satellites and got a position after only a minute or so, even after being shipped across 10 time zones!! And it picks up a good GPS constellation even under my carport.

My current complaints are few and minor: the audio has a hiss in it, and I see that Pumpkin has a power filter (free) to solve this issue. The GPS does not seem to have a "north up" setting, which I much prefer over "track up". Also, the existing GPS software has map colors that are very poorly chosen. It's almost impossible to see secondary roads, and I may have to change that software before all is said and done.

The physical unit is fairly large, around 4" vertical dimension, and it was a very snug squeeze in my Ford Ranger console -- but it worked.

The Android system is fairly conventional, but with all the apps and configurations, it's sometimes puzzling as to where to find a particular setting. Time will iron this out. Nice to have "home" buttons both on the touch screen and the push-buttons.

I'm overall quite pleased, ESPECIALLY for the price. I expect to have a lot of fun with this.

UPDATE 2017 March
After almost two years of almost constant "fixing", I'm about to give up. Support has been great, very responsive -- but there's a lot they just can't do. As of today:
-Bluetooth hands-free won't auto-connect
-Hands-free audio is garbled and unintelligible to my callers
-Sound system has background hiss
-Google Play has quit entirely, will not allow login -- no download of apps or updates is possible
-Some apps cannot recognize external SD
-Some apps can't work with GPS
-Some apps simply won't activate after loading
All I'm trying to do is use hands-free calling, GPS mapping apps, and play music. As of right now, it won't do any of those properly or at all. I have another unit that I bought after my initial liking this one, and it's just as bad.

So sad, it had such promise. The only time it ever worked right was in the first few months. After Android and Google changed their software, this poor product never caught up with them again.

Pros:
Fitbit App Synchronization

Cons:
Weight is inaccurate
Body fat % is VERY inaccurate

I'm a Fitbit junkie and I track my weight using a scale and my body fat using a handheld device I purchased off Amazon (Omron HBF306C) which is a great device.  The only inconvenience was having to hand write them on a notepad then manually input it into the app when I have time.  So when I found out that the Aria can do all of that by just me stepping on it, of course I didn't hesitate.

Well...  unfortunately I'll be going back to my old method because it's a lot more accurate.  My readings with my scale and body fat % were only off by a decimal compared to the gym equipment certified trainers use.

On the Aria scale I weigh 1.1lb less than I do compared to my other scale (which I don't mind) but my body fat % is about 7-8% more on the Aria.  It also doesn't really seem to change even after weeks of extreme workouts.

I can see the positive changes in the mirror, my clothes, my old scale and body fat monitor but I see little to know change when checking on the Aria scale.

This can be very discouraging and has I not had other tools, I could very easily see how someone can get disappointed and discouraged by not seeing any changes on the scale.

The concept is great but the technology has a long way to go.

Eh... Seems to be off by 4 or 5 degrees even after using Delta calibration (offset). Waiting for my DHT22 to arrive as from reading all the reviews it is the one to have.... Easy to use and lots of Sketches out there... Did arrive in 2 days... So 3 of 5....

Yes, I will have to chime in with the rest of the people. The analog stick (left on mine) is so jiggly and flaky that you can leave it sitting still in the Windows calibration screen and it will move all over the window by itself. Logitech of course, claims it's just worn out. Maybe, but I guess the other reviewers were right. Buyers beware!

I would absolutely give this 5 stars if not for one, very annoying problem - the extreme difficulty of reading the screen in bright sunlight. It's a beautiful display with notably higher pixel density than iPhone and in normal and darker settings that is very obvious. But catch yourself outside on a bright and sunny day and you have to squint to make out the details. Why, Huawei, why!? You're so close to making the perfect device. Please improve this in your next version!!

No there yet. It needs to be calibrated every time I want to use it.

So far, fairly impressed with this receiver.  Far better than the buggy Openbox S10 it replaced.  It does not have an Americas satellite database, so be prepared to enter your own.  The one challenge I'm still faced with is, where to set the local Lat/Lon for the USALS to function.  Once I figure that out I'd rate it 5 stars, but since the manual doesn't discuss it, nor have I found it in the menu tree, I got to take off a star.

Followup:  I finally did find the USALS settings, but it apparently won't work in Northern hemisphere.  The motor runs in the wrong direction to the limit.  I got to see if my motor can be reversed for proper function.  Otherwise you have to use DiSEqC 1.2

I am using this scope as a guide scope in conjunction with the SSAG.  But this little bugger took some troubleshooting before I had the 5 star experience.  First off I found it wouldn't come to focus without the Orion 1.25" extension tube (sold separately)  and both (included) extension rings screwed on.  I hear this thing can be fussy coming to focus depending upon the eyepiece/diagonal combo so beware of that!  Second, because this scope at 70mm is brighter and more powerful than the 50mm finder scope often sold with the SSAG, it means you need to make some adjustments in PHD2 guiding software from what the instructions recommend. The gain needs to be turned down from 95 especially if the only guide stars available are larger stars. Also the minimum motion needs to be turned up from .25 pixels to 1 pixel then slowly turned back down .1 pixel at a time to get the best resolution without the guider bounding back and fourth producing double stars.  As for the focuser, be sure it's all the way in (screwed in) leave the screws holding the autoguider (or diagonal if you are using one) loose so it doesn't spin while you are focusing, now unscrew the focus ring slowly holding your diagonal/guider in place until you reach focus then lock focus with the screw on the side of the focuser and also lock the diagonal/guider in place and you shouldn't have to mess with again.  It does seem the scope is out of balance but with an extension tube and the SSAG on the other end it seems to be much better balanced then. The rings are attached to a stiff arm and the 6 screws on the rings have a soft tip so as not to mar the finish on the scope. I can tighten these up really snug and so far, with my cords secure, I haven't suffered any differential movement between the guider and main scope and I am getting fantastic results. Because of the larger aperture at no additional cost in weight (than the Orion 50mm finder scope) I am seeing guide stars no matter where I point my main tube and have not had to readjust the rings in search of brighter stars. I have never had any trouble with calibration due to dim stars like I have heard the 50mm can have causing the user to turn up the calibration steps which works but in turn takes longer to calibrate.  All in all I am very happy I went with this 70mm guide scope.  It is good stuff once you make it work and I hope this helps you in that quest.

4.5 stars is closer to accurate. Make sure you follow directions to calibrate (AND save those instructions for next time).

First flight was awesome! For some reason I especially love the landing gear. The different modes for the 360 gimbal are awesome and allow you to get some really cool shots if you follow a line. The trick is going smooth when turning. If you are filming, slow it down... throw it all the way to the turtle on the remote. There really are a lot of amazing things about this drone. However...

I then put a micro SD card in the controller and realized that the spring to push the card out didn't work so I had to use tweezers to pull it out.

The camera seemed to have issues connecting to the controller. I did a calibration hoping that would help. It didn't connect but the camera started moving. I decided to turn everything off then back on after everything I tried failed. Still no luck connecting. I went into the pairing options and realized my the camera was no longer paired/bound to the controller. No problem I will just connect/bind it.

Nope... A password was needed. I then looked up information on the camera and found out that the general password is 1234567890. I was able to get everything working after putting in the password. Except, the camera was a bit tilted, even after multiple gimbal calibrations. I figured it might be the area that I fly in, or that the ground wasn't perfectly flat. I went to another location, used a level to make sure the ground was level, and did another calibration. It was actually a bit better, but still looked a bit tilted, maybe by 5 degrees.

At this point I was still willing to keep the drone. I could easily level in post (especially if I record 4K) and the only time a card was needed for the controller is for firmware updates and re-binding a camera every once in a while weren't huge deals.

However, on my 5th flight I was bring the drone in for a landing as soft as possible (in full turtle mode) and as the drone hit the ground, the camera and gimbal popped right off. They were held on by two, very thin pieces of plastic that were about an inch long. There is not a scratch on the drone... not even on the propellers. This was not operator error, but a sub-par connection.

The worst part is that I went to return it (to the store that rhymes with pies. Sorry Amazon, my impatience lead me astray - never again) and they refused to take it back and give me a refund for a clearly defective product. Now I am having to go through my credit card dispute department to get my money back.
