Mine failed within weeks just like so many others

Worked for two weeks then stopped printing black.  To Amazon's credit they shipped me a new one fairly quickly.  That was a week ago - we'll see what happens.  Besides the functional failure the quality of construction is poor- some might say "cheaply made".  I also felt some of the functionality, specifically with regard to scanning was weak.  The materials say you can customize the functionality eg the preset destination etc of scans and exactly what the buttons will do but the buttons on the scanner don't correspond with the software or the documentation.  Both email and voice communications with tech support resulted in them resending me the same useless instructions that an apparent language barrier made it impossible to get past. Epson used to make good products.  Now I'm not so sure.

The pump failed within a few weeks and I was left with a fancy fan.

Board failed less than 24 hours after being installed.  Replaceded with same brand  also failed right a way. Ended up with a sabertooth and have not had one problem

I have had three stop working within one or two weeks, It has great reviews so I kept getting replacements thinking I had a fluke. Done trying! I have these hooked up to a jet ski that is outside at my dock, but covered. Maybe they just can't handle the Florida humidity.

My experience is like many others. It worked well for over six months and then the vacuum seal apparently failed and it stopped insulating. My guess is that 100% of these will fail within a year.

I bought two of these, and one of them failed pretty quickly. This is NOT a product that you want to fail. Mine is packed way up above the ceiling fan, so almost the whole fan needs to be taken apart to replace it. And of course, you don't know if this is the problem or maybe it's something else (in my case, it was the receiver unit in the attic). Even if the replacement is under warranty (I didn't bother to check), it isn't worth installing another one if it's just going to fail again. There are tons of similar units available. The last remote I bought from another company had lasted 12 years when I sold that house.

Just like others, I bought 2 failed in a week, and the other just the other day.  5 days after return.  The cage on the inside falls apart.  Don't buy them!!

Every one failed in less than 6 months.  Please folks review after you use the products for at least 6 months, that goes for all products here.

It failed within a week of ownership. While I used it, it could not desulphate the UPS batteries that I had connected to it.

It only lasted a week for me! Don't know what to do I guess I will need to purchase from another company

I've tried two of these chargers and both have failed. The first after about a week and the replacement after about six weeks.

What is it with these chargers? Over ten percent failure rate. Wall charger technology has been around for decades, so it must be the quality control.

I've owned 4 of these units for about a year and over that period I've had 2 that have failed. One of those 2 failed units had very little usage too. It's not a mechanical issue but an electronic issue on both units.

So far every bulb I've tried worked, but in the 6 weeks since installing them, 2 out of 8 have already failed and needed to be replaced.

After letting them have the suggested charging time we put these in our garden they looked fantastic!  Then...one after one they started failing to the point where after one week we only had two of the six working.  I am hoping it is just the batteries so I can buy some...but really I don't have time (or don't feel that I should have to spend much time) troubleshooting something that I just purchased as brand new, and its not just one, its 4 of the 6 we bought.

I took a gamble after reading the other reviews of a high failure rate, I should have known better.  What a let down.

3 have already failed and I've only installed 10.  30% failure rate is not good.
Update 4/4/17 - 4 more have failed.

This item worked for about a week, then no longer functioned. The device will no longer dim the attached LED strip, although it still passes power to the strip at full brightness. It's too bad that this failed. Maybe you'll get a good one. I got a lemon. But, the thing is, this is so inexpensive I may just try again with another one. (I realize that this is the definition of insanity, but I want a dimmer for my LEDs.) Can't give it one star as I don't "hate it;" I'm just disappointed.

I'm not sure what's going on with Anker lately (I've been buying, recommending and using their products for years) but this and an Anker 40W 5-Port Family-Sized Desktop USB Charger with PowerIQ I bought have failed within a month of use.
