Lasted a week, after only using it about 4 times, it stopped working completely. Note that I didn't drop it or did anything that could have broke it happen.

I only used it about 3 times, after that for some reason it just completely stopped working.
Definitely got what I paid for.
Never thought that would happen, but maybe I just got a faulty one...

The product worked well, but stopped working in the 4th week.

I thought it'd last maybe like a week, but it was cheap, so I bought it. Ended up working perfectly, though, so I'm really pleased!

Didn't hold up very long, having to replace even though it wasn't use very often. I would try another brand

Broke after one week. Only used maybe 3 times for frothing coffee, went to pick it up by the metal end and it just fell apart!

It Lasted a week.  I had to go out and buy another one.  It was a waste of money and my time.

WAS fine until it stopped working a week later. Perhaps the one I got was faulty. Not sure. Product seems rather cheaply made.

Installed on my Anet A8, suddenly died (mid print) 4 months later, only used it about 30 times. Several loose bits found inside after it failed.

 You get what you pay for, Chinese junk.

It broke after a week of using it and we barely even used it. Unfortunately I bought it because the other reviews seemed so positive ... oh well waste of money

It was great fun while it lasted - about 4 weeks! We were using it as usual and then it just stopped erasing. It will still write, but pressing the clear button only makes the writing faint, it does not clear the board. Sad day. I had registered the product with iMPROV, and contacted them about a warranty repair or replacement, and got no response. I would say "you get what you pay for", but I think it would have been cheaper to buy 10,000 pieces of scrap paper.

Poorly made, i had it a week before it ripped.

This worked great for 4 months and just died yesterday. I'm so disappointed as I had zero issues until that point. I used it frequently, 5 days per week at my job. Worth the $12.99, I suppose.

It worked ok for a week, then it stopped all together.  I am sending back to get another brand to try.

It works good but only lasted 3 weeks. For the price, I figured it would last longer.

Fell apart with minimal use within a week of getting it.

Crapped out on me after about four weeks of use. Four weeks of use at Burning Man over three years, with most of the circuitry covered in caustic lakebed dust the entire time. So I can't blame it too much. Seems fine for the price, will probably replace it with another of the same one. (It is junk, don't get me wrong.... but what do ya want for $10?)
