This fan stopped spinning months after purchase. If you open it up you can spin it and it works but who should have to do that.  Junk, don't buy.

Stopped working within a month of buying. Beginning to wonder if I should buy any electronics stuff from Amazon. This is the second such instance

I bought the product and was extremely happy with it. Easy to use, and did what I expected it to do. Then after a couple of months, it just stopped working. Wouldn't charge or turn on. The company sent me a replacement because I was still under warranty but even that stopped again working after couple months. Other people in the review section seems to have the same problem as me so I have to recommend using your money elsewhere.

After a few months it stopped working.  Not worth the money I spent on it.

I've had this for a little over 2 months.  It has stopped working.  I would not recommend buying this product.

Update:  Amazon is going to credit me for this product so I can purchase another one which works.  I've updated my review becuase I really respect that Amazon will stand by their products and I can repalce the non working product with a working one.

Worked well for a couple of months, then just stopped working at all, even with a fresh battery replacement.  I can't endorse this product for long term use.

Worked for a couple months and then gave out. I usually just buy these every couple months since that's about how long it lasts.

It stopped working after a few months, and it is too late to return it. Now I have to go through the manufacturer's warranty process - bleh!

Our unit quit working after only a couple months and we are past the return time period.  Now I'm going to try and go through the manufacturer to see about getting a refund of getting it replaced with one that works.  This should be fun.....
