Run from this!  Did not perform as expected as it would not match or synch up with my LG TV.

Avoid avoid avoid.  Like others, I picked this up thinking it would be an upgrade for the devices that can leverage 5GHz, and my 120Mbps+ connection through Comcast.  Hooked it up and everything connected to the 5GHz but slooooooowwwwwly.  The 5GHz connections ranged from 1Mbps to 10Mbps while my direct connect laptop was getting 125Mbps.  It was worse on mobile devices.  Never could get the 2.4GHz connections to work (important if you have kids using Nintendo devices!)  despite the cut/paste jobs on steps to fix the issue called support by Linksys.  I'm an IT professional and couldn't make this work.  Returning it and just running to the store to get the standard $80 wireless router from Walmart.  I really wish this worked as expected but this just isn't ready for prime time.

Terrible! There is NO way this power supply puts out 30A continuous. It might peak at 30A one time, then its poor construction damages your equipment with an overvoltage. I had a 70x2 watt audio amplifier hooked up to this thing, operating at a low to moderate volume for less than 1 hour, and that was not even a continuous hour. The onboard amp meter showed about an 8-12A draw, well under the rated current. Then the onboard volt meter pegged at 20 volts. Luckily, I was right there to turn the power supply off. I disconnected my amplifier, then turned it back on and checked the output voltage with digital volt/ohm meter: 29 volts! Not good when your attached equipment is rated for 14.4 volts. Obviously there is no over voltage protection (or it does not work) with this unit. I agree with the other reviewer, if you have to stencil "Quality The Best" on the front of it, you get a bad feeling that it's quite the opposite. I should have known better that I could get a decent power supply at this price point.

Bought this from a local shop, not expecting to see the results it claims (1000w) but was hoping it could still push 300w around to some speakers i had. amp was very very under performing and on full tilt couldn't even come close to powering my fosgate 6x8's. long story short this amp does nowhere near rated power and besides that i also noticed a distinct whine over the rca inputs only from this amp. i took it out and troubleshooted it with another system to confirm this as well.

When considering Amcrest branded products, RUN!  Run fast. These cameras will give you an awesome picture, but they are almost impossible to keep running.  They lock up, fail to respond, etc.  And to understand how to try to resolve your problem you need to be VERY computer savy and technologically oriented.  These are not for the average homeowner.  Probably a very capable camera system but if you can't understand how to run them, then whats the point. Amcrest Technical Support will get you up and running for awhile, but you'll be down again. Recent calls to Tech support I felt like they were over-run with problem calls and seemed very impatient and quick to get you off the line.  If you are looking for a plug and play security camera - look elsewhere!

This card didn't live up to expectations. I bought it because of the price and the write speed. It's listed as 90MB/s Read and 60 MB/s Write. My own testing showed 80 MB/s Read and 35 MB/s Write. The Read speed was in the ball park but the write speed was way off and unacceptable for my needs. Next, I took a few shots and my camera screen went black and the camera locked up. I removed the card and attempted to format it on my Mac and it wasn't recognized by the system. The camera restarted and is functioning normally. I'm returning the card.

Bought this to address some stability issues with my other wireless adapter.  This one was even worse, brand new out of the box.  Would randomly disconnect and then reconnect, making gaming a nightmare.  I would get around 53 Mbps speeds with my old adapter, with this one I don't even top 12 Mbps, despite the description of this product which states it can handle 150 Mbps. And I had it plugged in less than 2 feet away from the router.

Overall, this product was slow and disconnected every few minutes.  Can not recommend.

Does NOT work as expected nor stay in place with the slightest variation in temp!

Maybe closing a window tight down on it might work - but as far as vertical applications - forget it. Backed rating of 2009 off to a 1 start -
*******************************************************************************

Split as directions noted - applied - door frame gap during warm weather - loosened the next day - poked back in w/screwdriver for next 3 days - seems to be holding now colder - but do find it didn't work for what we needed/  and it takes more than one package to 2 do 2/3 doors -

Still rec. as Quality company -

Returning is as painful as ordering this crap!
Run far is all I can really say.

Bought this to replace an old router and figured it would be a good mid range device.. out of the box was having power cycle issues would just reboot it self at random so read up on the reviews and saw some were able to get past this with new firmware so went ahead and upgraded that and completely reset the device just to be sure no issues could be related to future problems. same outcome, would not stay connected and sadly speeds were not even that much faster then my 4+ year old router. started looking into custom firmware but as options there were slim as well just packed it up and returned it. would be great at this price point if it performed even half as good but couldn't even do that. would stay away from this device.

Ugggh. Don't buy this if speed is what you are looking for. I was moving up from a 64GB Extreme to this guy. It took about 10 hours to copy my 57GB of data from an SSD (I first copied the data from my 64GB Extreme to my SSD so I wouldn't saturate the USB channel) to this drive over USB3.0. The drive is fast copying a single large file (write times around 35MB/s), but it slows down to a crawl (sub 1MB/s) when doing lots of small files. I benchmarked this guy against the 64GB Extreme and it performed very poorly. Even reading was much slower. I am quite disappointed as I guess I was expecting comparable performance to my 2 year old drive, what with the advances of technology. Go for the 128GB Extreme drive; I wish I did.

**2nd update 02/27/16**

Performance is degrading, doggy/laggy response. Frequent reboots to fix buggy performance. Poor update/patch cycle. Changing review to 2 stars from 4. Basically, "avoid" this device. Get something worth your money that actually works. Very disappointed in Asus.

Received and did not work at all! Shop elsewhere, stay away!

Had to return this - obviously my Verizon DSL is just too poor a service on its own to be resolved by this product, no matter the cost! I did run the download test(s) available, both before and then after the eero was installed. It definitely increased my available speed - the biggest difference was it shortened the 'delay' from 167 to 9! But then I started getting 10 sec rewinds during streaming and the player still hung on occasion, etc...

On the one hand, if you can spare the cash this definitely has the potential to improve your wifi. If you have poor service at the source, like I do apparently, while this does improve the wifi signal it doesn't resolve the source issues and I just couldn't justify paying out the money. Low return for high cost of investment - sent it back.

The short of it: If you can't trouble-shoot your own equipment then forget this thing. It's plug and play on the surface but evil lurks somewhere, inside the unit or the drivers, not sure.

The Good:

-Performance is great.

-Keeps trying to connect to the neighbors network so the range is super (and their network is G only, not sure where their router is but at the minimum 30 feet through 2 walls, a wood fence and lots of foliage).

-Nice long cord (5 feet or so) and docking station so can be positioned sorta wherever.

-Simple to setup, follow the instructions and 'boom', connection!

-Cheap.

The Bad:

-You get what you pay for in this case.

-'Boom', connection! may require a little fiddling in Device Properties but that's standard so not really a 'bad'.

-Keeps trying to connect to the neighbors network wiping out the SSID in device settings (finally had enough and told them how to change and hide their SSID and things good now).

And the ugly:

-Using the boxed drivers V1.0.0.0, utility version V1.0.7.4, firmware V1.0.0.0. Had the thing for a month now and twice already the drivers, for no apparent reason, froze the system and on hard reboot WinXP would lock up to instant black screen while booting and would only boot in Safe Made with networking disabled and normal mode only if the actual USB connection was physically disconnected, not just the stick removed from the base. Fixing this requires booting into Safe Mode minus networking or normally with the plug unplugged and removing the drivers then rebooting and re-installing the drivers. Updating drivers could help the problem but  finding them on their website is sorta a nightmare all its own for time limited people.

-The SSID wipe never happened until the the first freeze and won't go away.

-Prior to the first freeze, on a couple occasions the software would claim the device wasn't present unless I unplugged the stick from the base and plugged it back in.

-Device won't run without the shipped software after the first freeze. Can probably fix that but don't have the time.

Summary: There's flaws, it's cheap, works fantastic for the most part but when it don't work, at least in my case, nothing else works either. But compared to the card it replaced I still love it. But if you've ever called Tech Support to try and fix a problem then buy something else because this will be a pretty shrink-wrapped box of pounding migrane waiting to happen. Just my opinion.

I try to be as positive as possible, but not warning shoppers about this product would be a dis-service.  I own a retail store that sells and installs high end a/v equipment.  I am very well versed in how products like this should perform.  That being said, my opinion of this product is quite low considering the following points:

1) Performance of the usb wireless link is ridiculous.  I cannot believe the manufacturer would put their name on it.  With the devices less than 3 feet from each other they would constantly drop out.  This in itself makes the product a non-starter.

2) The included software is tricky to navigate at best.  It integrates (somewhat) with windows, so you can't really tell if you're working with the GUI or with windows.  Not a deal breaker, but definitely not user friendly.

3) Out of the box resolution for the second monitor is 480p max.  If you stop there its unviewable.  After 20 minutes of updates to the software and 3 computer restarts, it does get better, but i expected a new product to either be up to date, or self updating upon installation.

4) in extended desktop mode this thing is ssssllloooowww!  Its so slow you cant follow the cursor on the send monitor.  Another deal breaker for a product with the claims they make.  And this is NOT a pc issue.  I'm using it with a brand new dell 6420 with 8g ram and 2.6g i7 running win 7 pro.

It's a great concept with poor execution. Thank goodness I got this from a reputable seller (AMAZON) that has a great return policy, otherwise this would have been a waste of money.  It's already in the box and labelled for return now, and I can't wait to get it out of my possession!  Sorry to be a party pooper, but I'd recommend you save your money for something more well engineered.

Difficult to install, wasn't streamline in any capacity. Poor performance - DO NOT PURCHASE THIS ITEM - Returned item.
Purchased TP-LINK Wireless AC450 Nano USB Adapter at the advice of my IT person - it worked like a rockstar, quick install and instant results.
