Works surprisingly well. This thing has been through it all heat, dirt, drop damage, a hurricane! however it still works fine. it's what is described so if you want that, get it. (only works when the sun is out, stronger the rays, stronger the out put, no power storage).

Surprised at how well this works. I'm terrible at using a normal push saw, so this was a godsend that it exists.

I'm surprised at how well this works. I've tried other things in the past and been disappointed in them, and in the end they were a waste of money. This however is excellent and I may buy another.

What a surprise! This USB drive works really well for such a small thing.

First thing I did when I got this was scan it for viruses and malware using Sophos: there were none. I also didn't notice any bloatware, and the device did not require me to download or install anything.

I did find the instructions a bit confusing since there was a bit of a language barrier in the translation. In short:
 extend the USB connector
 leave in OFF state.
 plug into drive
 turn ON when you are ready to record. Once you turn it on it starts recording. To stop, you simply turn it OFF. (Unplugging it will work too, but I recommend using the OFF switch first.)
 a .WAV file is made for each time you turn it ON the OFF (while powered.) You can go into Explorer/Finder, then "Record" folder to see your .wav file recordings. PC users: just double-click to listen. Mac users: you will likely need to download the free VLC Player app to listen to .wav files, unless you already have an app for them.

The quality of the recording is pretty good! I tried it in a quiet and noisy room, and from different distances. In all cases the mic picked up everything, though if you were using this with someone who talks very quietly and is more than 5 feet away, you may not pick up there voice.

The recorder says that it will stop recording if there is no noise. But, I found that normal office room noise kept it going in virtually all cases. They made it sound as if it was voice activated recording, but again, I found that it just kept recording the room noise. I wasn't able to find out what decibel it would stop recording and start again.

Situations this would be great for:
 meetings (though a lot of people talking over each other gets difficult to differentiate them on the recording since they seem to blend together.)
 dictation
 sending audio files via email
 in-person interviews
 and seriously, it looks like a USB drive, so you can use it to secretly record conversations around you (though review your local laws on this.)

There is a funny little situation that arises when using this:
When the device is plugged in and OFF, you can see your recordings in the Explorer/Finder. For Mac users, the device is mounted. But, once you turn it on the device unmounts and is removed from Explorer/Finder as a device. It then becomes a simple USB powered self-contained recorder. Turn it OFF and it becomes a simple flash drive again.

I tested it on a Windows 8.1 ThinkPad laptop and the latest MacBook Pro running Yosemite. It worked on both following the instructions above. And as stated above, Mac users may need to download the VLC Player app to listen to .wav files since iTunes and Quicktime do NOT play it.

I recommend this recorder for anyone that needs to do one of the above situations. -1 star for the incredibly outdated packaging (it lists Windows 98, ME, XP, and 2000 as compatible, but not Vista/7/8) and the difficult to follow instructions. I would have also liked to see the recording light be a little more obvious. The way it is now it is very difficult to see unless you look directly down into the pinhole, and even then it's hard to see. That, and it's form factor, make it a great spy recording device though. Also, Mac users will get pestered with the "Disk not ejected properly" message each time you turn it ON.

I received a free sample of this product to evaluate and provide an unbiased review.

I didn't think there was anyway this was going to work as advertised.  I was wrong.  It works very well.  I have no complaints and I am very impressed.

I am pleasantly surprised.  For a lower-end model it does everything well.

A bit flimsy -- but it does work. Surprisingly!

Works really well.  Didn't expect the ink to flow so smoothly.

Works surprisingly well. We used it to after killing a greeb algae bloom.

Works well and the outdoor temperature receiver works surprisingly well.  Even through walls it picks up the signal without a problem.

Works surprisingly well for an unpowered nozzle in increasing the force of the spray.

Wow.  I didn't expect much for the price, but it works perfectly.

I wanted a solar pump to circulate water in a birdbath to attract birds and keep mosquitoes from laying eggs.  I read reviews from others who had trouble with this not working unless in direct full sun, and maybe mine is a fluke, but it works much better than I expected.  As others suggested, I carried it out to the birdbath upside-down, but even at that, I could feel the pump pulsing on and off.
Once I placed it in the water it began to work after about a 1-2 second delay.  It pumps just fine even when it's partially cloudy.  As a matter of fact, today it's that mostly grey overcast summer sky, and it's pumping just fine.  When it does cloud up, it doesn't pump constantly, but pulses on and off.  That's actually better performance that I expected and more than satisfies my requirements.
My only problem now is how to keep it from moving around so it doesn't spray all of the water out of the basin.  Unfortunately the suction cups don't stick very well because the birdbath basin has a rippled surface.
Overall, I'm very happy with the purchase and would definitely buy it again (as a matter of fact I bought two of them).

Works better than I expected. Functions properly and charges surprisingly fast!
