Microsoft Lifechat ZX-6000 (No wires but poor quality)
584883
I purchased this product with the goal of recording the audio from my lectures as part of a Camtasia file. Before purchasing this product I used a traditional desktop mic to record audio. I wanted the Microsoft Lifechat so that I could have the flexibility to walk around the classroom without causing variation in the sound and audio quality.

The Lifechat does what it says it does. I was able to record audio at a consistent quality throughout the large lecture hall. However, the quality was pretty poor and I needed to spend a bit of time enhancing the audio in Camtasia to make it playback OK.

The biggest problem, however, is that the wireless mic caused my audio and video files recorded in Camtasia to be out of sync. I recently read that this is a typical problem with wireless recording devices.

I had to discontinue use of the product.

Comes without adapter cord for micro USB and without instructions for which application to use or download. I tried several from the Google Play Store. I found CameraFi worked the best. Picture quality is very low. Its best quality is with close ups. All other quality is muddy and fuzzy at best. Don't expect Go Pro or Mobius quality.

I have had nothing but problems with this device since I purchased it.  First, Polycomm has not release a Vista x64 driver for it yet.  Through some research, I have found that they have a Beta program for a Vista driver.  You have to email tech support requesting to be included in the beta.  The current version of the beta software is 2.9 which is 8 months old.  The bigger and the ultimate reason for this low rating is, the sound quality.  I have used this device on multiple conference calls and almost every time I received a complaint about not being able to hear me.  I have dug through sound settings, device settings, and the registry looking for anything that would allow me to increase the Mic gain and nothing worked.

Perhaps this problem will be resolved with a new release of the driver software, but until then, do not use this device with Vista x64.

Side note: I have not tried it on any other OSes and it is likely that it performs well under those that use the production drivers.

I used LW2712 for a few years and loved it. It was broken a few months ago. So I bought this LW1742 to replace the old LW2912 (I do not think Lorex still offers the old LW2712 model). When I first opened the box, I was quite happy to see the metal camera housing (LW2712 used plastic housing for camera). The metal camera housing gives it a quality feel. Installing both cameras took about an hour. Then I was SO extremely disappointed to see the performance. Here are just a few things that frustrated me a lot:
1. The video does not show good resolution. It shows a lot of mosaic blots. It seems like there is a lot of cloudy smoke roaming around in the video.
2. The audio (LW2712 has two way audio for talk back, while this LW1742 is only one way audio) barely works. You can hear people talk. But they are like background noise--it is extremely difficult to distinguish what they are actually talking about. This is such a big disappointment. The audio for LW2712 worked so much better than this one, and I thought technology is improving these days....?!
3. The worst thing is the motion trigger. It works fine at day time. However, when it is night time, Channel 1 camera gets triggered constantly without any motion. Channel 2 camera also gets triggered every 10 seconds or so without any actual motion.
4. The recorded video does not play back on my computer. I can't use it. It does not work properly.  Will return it to Amazon.

customer serivce - live chat --which is practically useless and utterly frustrating!!  the device was good for 6 months then stopped working.  spent more than 4 hours with 6 different support persons to no avail.  finally they agreed to send me a new device but charged me $5.95 for shipping and handling!!

The seller requests return , however , I decided not to return because the seller is from China and would last approximately four months to replace . Do not buy it , I read that happens to the cloned phones.

Very low quality, manufacturer phone lines (who supposed to provide support) are disconnected

I decided to try these out before I gave them for gifts and I am glad I did. I couldn't step two feet away from my device before it crackled and lost connection. I would be better off using a wired headset because I eas pretty much tied to my device anyways. I got them at a good price but paid for it in quality. Very poor quality. I hope they take them back.

Followed directions, tried firmware update, people in chat can't hear me; mic sounds worse than Kinect at a distance, unacceptable for the price.

Crappy knockoff of LG HBS Bluetooth devices. Goes from fully charged to fully dead in under 2 hour of phone music

Call quality is great. Don't know how the battery life is on the headset because I keep it in the charging case when not in use, but the battery in the charging case seems pretty pathetic, 3 days of standby with maybe 15mins of talk time and it was dead.
Every time I check my phone to see if this is connected it is, but about 75% of the time I get a call and go to grab my headset, it says "pairing"...despite having been paired earlier that day - makes it hard to like this when I can't use it most of the time.
DON'T USE THE LOOP ON THE CHARGER TO HOLD IT!!!! I had it clipped to my belt and freaked out when I thought I had lost it, when I found it the little nylon loop had broken, now I don't know what I'm going to do with this when I'm not talking ><

I have used the phone for 3 months now.  I regret every minute of it.
1.  Battery, despite being a lithium-ion type of 900mAh, can not last a day.  Brand new.
2.  Takes forever to find my wifi and sign in.
3.  Once in, I can call out, but people using skype can not call in.  And when it does come in, it is a miracle.  I would rate the success chance is that of 10%.  Tested over several weeks with my relatives in several cities in China.
4.  Reported the issue to Netgear, they asked me to refer to Skype!  Hah hah, what does a failed product has to do with Skype is beyond me.  I have Linksys cit-400(one handset failed on me) and Philips VOIP841 (highly recommand) in my household and they never dropped a skype or line call.  And they connect right away.
5.  Sound is weak.  Both ringing and sound volume is low.  Hope you are not old or hard of hearing.  Oh, there is no speakerphone either.

I wish I would have returned it when I had the chance.  The sad part is that I got 2 of them!!!  I am still going through the Netgear web support in an effort to say if they will respond after they attempted to "pass the buck" to skype.  Great service, netgear, so far, .... NOT.

Update 03/2010:
Upon complaining to Netgear via writing, I was provided an RMA #.  Sent the defective item back and got a replacement handset.  So far, so good.  It does not have the latest firmware (don't upgrade).  Much better and reliable.  It can find wifi and receive calls.  It has been over 3 months now, so far so good.  Thus, I am amending my rating to a 3.

sony Xperia z3 is a good phone in general but
do not buy from legend wireless. mine came in opened box but decided to keep it and hope it will work just fine. but it didn't. just after a week of use, problems started to appear. it restarts by itself many times. the screen will sometimes flicker. popup window of some white noise video or something. decided to factory reset then upgrade the system software. the software problem seems gone but now the hard keys are not working. now I'm returning....

Product has many nice features, except clear calling.  Having only had the phone for a week or so, several times people say my voice is all broken up and can't hear me.  Also, the backlight flickers like it's shorting out.  Also, when pressing some of the buttons it crackles and flickers like it's shorting out.  Sending back ASAP!!!!!

After trying different models and having to return all six, including the bad ones sent as replacements (one that was water logged and fogged from the inside), I recommend you avoid this camera for anything more than plugging it directly into your router or switch.  Wireless does not work, and when it does out glitches so often that the motion detection is unless...not that the software works, either.  I tried it with Blue Iris, which is better, but the cameras themselves are the real problem.  Need wireless?  Spend more and go with Vivotek or DLink.  Good luck!

UPDATE: I am still having non-stop connection issues. I emailed Yi support through their website and through Amazon and they never responded. Looks like I am stuck with this paper weight. Spend the extra $ and get the Nest/Dropcam camera.
WiFi isn't reliable and playback is sketchy, signal constantly drops out which is a problem we never had with our Dropcam in the exact same spot. You get what you pay for, no miracles here
