Works, but has frequent disconnects. Nicely priced, but better products are available but for a lot more money.

Works as advertised, but disconnects too often. The free download software works, but there are better options that cost a few dollars. It was nice to view all the provided information on my phone and capture for later evaluation. It works, but I'm sure that there are more reliable products.

Pretty clear on both ends of calls, but doesn't have good range (compared to many others I've used over the years) and disconnects and reconnects all of the time.

This works for its intended purpose, but not reliably in an office setting. The drivers do not play nicely with Enterprise software.
I have  the Kinesis Freestyle 2 Blue wireless keyboard, and it will periodically disconnect from this dongle arbitrarily.

I have paired my keyboard to other native Bluetooth devices, including a Galaxy S3 smartphone, and have never had a drop-out occur. This dongle also cut out while playing video games at home, though it has only happened once. Once is one time too many.

Kinesis recommends the Knivo adapter instead.

Product is okay, but there are much faster modems out there. Plus the first one I bought needed to be sent back due to defect.  I would not buy again.

Good but occasionally has lost connection (audio kept playing but sound did not).  Also, though it supports bluetooth, bluetooth audio is too choppy to be useful.  I was hoping to be able to use my headphones with this.

Not terribly impressed with this booster. It frequently loses connection with our main router and requires resetting, inspite of the fact that it is almost in line-of-site with it. Maybe I was just unlucky and got a faulty unit, but I don't really fancy buying it again and having the same issues.

This is only my second wireless mouse.  While this one is better than the $10 cheapy I bought before, it still isn't as good as I hoped it would be based on the glowing reviews I read before buying.  The main issue is that sometimes (often) it loses the signal to the computer (blinking red light), and often with no obstruction and very little space in between the reciever and mouse.  A little annoying when you are trying to get work done :(

Issues. It disconnects frequently . I have to unplug it and plug it again  and configure it again. Very unstable.

It's a decent USB 3.0 hub, but not spectacular. When I've connected some USB 3 portable drives, they frequently disconnect when they don't when they are directly connected to my laptop. Like many hubs, the cables for connected devices don't fit flush with the device.

I bought this for travel primarily, and am looking for another option for my next trip. The mess of cables, large transformer, and disconnects means it's not as convenient as I had wanted.

Constantly disconects and reconnets on both my machines. Might be the machines, but I doubt it. Works well other than that.

It's low profile and well priced, but doesn't always seem to stay connected to my computer. I'm not sure if it's an issue of an odd USB port on my computer (the Surface Pro 3 USB port doesn't ever seem snug, especially on something like this where the cable's not quite long enough for the whole adapter to sit on the desk) or a bad connection between the cable and the ports. 90% of the time it seems to work fine, but 10% it won't until I disconnect and reconnect. Unfortunately I needed it for some critical peripherals that aren't very tolerant of lost connections, so I can't recommend this product.

Sound is good but it constantly disconnects and stops playing music. We use this in our sons room and stream music from a phone while he sleeps and at least once a night we have to go in to shut the speaker off and turn it back on so it reconnects. This happens even if were in the next room. It also occasionally takes a while to connect once its turned on.

Meh. The connecter is really bad. If you don't mind having to move the connecter every few seconds due to it losing connection to your device,  I'd recommend getting this. Otherwise,  stay away.

Product works, If you had more to spend then get a better AC router but this one is not too bad. The bands are alright. Drops signal barely but I think it has dropped and when it does, it is very annoying but I think every router occasionally does, right? anyways, It is okay for the price I paid.

Connection breaks at times. Coverage is good ... but not as good as advertized.

This should really be a 2 1/2 star rating, not 3. Worked well for awhile with my PS3 and ChromeCast, but seems to be dying. Occasionally, the picture will just drop out, and my speakers will make a high-pitched squeal for a quick second. A few seconds later, the picture comes back, but it will sometimes keep doing this. Physically switching to another HDMI port will help, but I think more of them are dead than alive at this point. I kind of expected this for $40 bucks though.

These work, but like another supplier, the connection gets loose after several uses and then they won't work unless you wiggle the cord and situate your phone so that the connection remains for it to charge. The price was inexpensive enough so I'm basically using them up until they are all gone. I have found another supplier and am happy with the cords I received from them.
