Works, but isn't instant

This thermometer is slow in registering the final temperature.

Works as advertised, but not as useful as I imagined it would be.

I bought this to power my home air compressor to pump up my bicycle tires. It does work, but the odd thing is I have to turn it on before I connect it to to my bicycle tire valve. If I attach the valve first and then turn on, for some reason there's not enough power for it to start. But with this minor workaround, it does work fine and I can pump up my tires effortlessly in a minute.

It works, but the re-charge rate is VERY slow.  The added bonus, though, is that I can use it in my car.

It works, but it's not the one I was looking for

It works, but can be slow at times based on how it is positioned within my room.  Not sure if it is the unit or the way my family room is setup and/or the wireless router it's attached to in the office.  Made it easy to attach my TV and DVD players to the Internet for content though.

We bought these as a cheap way to take the place for our broken leap frog device.  We are learning that you get what you pay for. They work, but the response time is horrible (push the channel button on the remote and have to wait like 2 seconds before pressing again or it gets all bogged down).  Don't expect to do anything quick.

Works well, and works fast. The speed of transfer wasn't instantly quick, it had to build up slowly though.

This is a good, cheap way to get minor scratches out of a disc.  Though it never worked with just one buffing, it does eventually work. I even got some more serious scratches reduced after an hour of repeated buffing, but the disc still skipped a little. One thing the instructions leave out, how to remove the disc from the device (you have to turn the handle backwards).

As many reviewers mentioned, this definitely does not charge phones quickly. There were times where my charge actually went down while using this. And you have to feed it constantly. But it does its job, and if you were in a bind, this could be pretty useful in several ways.

It works.  It's cheap.  Why only 3 stars?  Because the connection isn't very good.  It likes to pop out/disconnect because it's shaped slightly differently.  I have to work it a bit to get it to charge properly because if you put it on then set it on the table not carefully, it'll likely pop out.

Otherwise it works just fine!

It works when it wants to, but it could be my controller so on account of me not really knowing. 4 stars

Does the job done, not the best experience on iOS, but it works

I bought this to put in my car (I plugged it into my car's USB port, and the audio out into my car's aux in), with the intent of being able to easily stream Bluetooth audio from my iPhone 5 into my car.

It does work, but with one (semi-major) caveat. When I get into my car, the Xtreme unit is on, but it doesn't automatically pair. I have to manually power it down (takes about 4 seconds), then power it up (takes another 4 seconds), and then it automatically connects to the phone. This is a bit of a pain. Anytime the phone leaves the range of the car (e.g. I walk into a store) I will have to do this power-down-up routine in order to get it to pair.

I wrote to customer support and they said, sorry, that's the way it's programmed, there's nothing you can do.

For that reason I'm giving it 3/5 stars. It works well in all other regards, and at its price, is a great value for adding Bluetooth audio to your car. It's just not as automatic and seamless as one would wish.

I wish it would drop the food at the same time everyday but there is no way to time it exactly, there is a slight delay from one drop to the next.
Other than that, works as advertised so I don't really have any complaints...

It isn't the fastest method to charge but it does work well.

Works ok, not excited about it but not disappointed
