One of four worked; three of four failed.  These COULD be great but...

First one:  Awesome!  light.  I didn't care that it doesn't scrunch all the way back up.  So I bought one for the back.  Second one - fine.  Then the first one popped a puncture - within about a month.  I replaced it.  And the second one punctured on the first use!  I replaced THAT.  And the third one (mind you, the fourth of these things I have bought) cracked right out of the container.  I was attaching it to the hose bib and the female end just cracked.  No way to repair that.  I am SO disappointed!  These would be so handy if they were only a little better quality!

high defect rate. Had two of three that wouldn't work

great idea.  two of the three work, so that is a bummer.

Had good luck with these before. Got one that went defective after one month. The others seem to be working just fine.

One did not work, other one works great. Better to buy in bulk in case one does not work.

Some work, some don't, Some work, some don't, Some work, some don't, Some work, some don't, like I said, 2 out of three barely work, you get what you buy.

I ordered a few of these to give as gifts to family with my wedding photos on them. Three out of four seem to be working fine, but one has completely failed. All of the photos disappeared from the drive, and the drive can no longer be read, written to or even re-formatted. These are nice to look at, but I highly recommend having backups of any files you save on them.

Bought and installed 3 of these. Of that 2 worked and 1 failed outside of Amazon return window. I would love to have the third and be able to give this a 5-star review, but I can't at this point.

One didn't work ....aND while I was immediately promised a new replacement, I never received one.  The other two work great.

This one works tooooo.  Oh my 2 out of  four.  What are you going to do about the other two items that don't work??????

I am sure these are great when they work but I have had two defective ones. They would not work at all. Sent them back and won't reorder.

2 of the four did not work. Thought I had printer issues when I tried first two cartridges and reloaded drivers. Same two did not work. Was going to order new printer then tried 3rd on a lark. It and the 4th worked. Reinstalled 1 and 2 to verify and they were defective.

Bought 4, 1 was dead on arrival. The ones that worked were great.

Only 3 out of 10 of these worked for me which was disappointing, but the ones that do work are fine.

2 out of 6 don't work. Would return but already gifted 2. I hope those work but have no confidence
