The reversible mechanism broke after just a few uses.

The belt looks nice but the mechanism that lets the buckle reserve completely broke after 2 months.  I wore the belt once per week while playing golf and now it is completely useless.  Amazon won't let me return it because it has been more than 30 days.

Update:  To the credit of Under Armor, I called and spoke to them.  Although I had to wait about 15 minutes on hold, they did agree to refund the price so I could get a new belt.  So I credit them for standing behind their products.

Well, from many previous reviews I knew the winding mechanism was easy to overwind and break easily, but it sounded like you could open it up and reset it yourself so I was willing to buy it. Using it was an ok experience. If you don't take your stuff out right away, it'll run down and you have to wind it more often, no biggie. I was always careful about how much force I used when winding it, but nonetheless after less than a year, sure enough I  overwound it, so I opened this page for the directions on how to open it and reset it. Unfortunately, they made it so you can't get at the mechanism anymore. After you take out the 3 pins and open it up, you find the mechanism is now sealed inside a metal can glued tightly to the top rim. Completely inaccessibly and thus trash now, after less than a year, from the simple mistake of accidentally overwinding. I imagine I could return it under warranty if I can find the paperwork, etc, and then deal with the shipping of this heavy item, but yet again another hassle on an item that simply isn't made very well at all.

I returned the grip strengthener after a couple uses because a piece of metal snapped and made it unusable.

I love the concept of the collapsible containers for storage, but I used mine only a few times before the bendable part separated from the hard plastic.  Very disappointed.

Very disappointed.  first, it's a very awkward grip, second, it's incredibly easy to pinch your hand on the mechanism.  But the worst offense is that that the thing broke in less than 10 uses.

I thought I liked the product until it broke after a month. I'd only used it three times and on the third time one side of the holder part easily broke (both "claws"} when I was putting my camera in it. For the price, it's really not worth hassling with a return.

I purchased it and only used it a handful of times and now it does not work.

broke after the first use, or it just flips over immediately, probably have to buy another and then use this for spare parts

I'll be 100% honest - I was in love with this hose until it broke a few days ago. It was light weight and extremely easy to manage. I've had it about 5 months and only used it a handful of times (since it's been colder weather and I haven't needed to water my flowers). I originally gave it a 5 star rating but now have to change it to a 1 star since I only got about 10 times of use.  Extremely disappointed :/

Well, it looked nice. And for a brief, shining moment, this bag was very functional. Worked for a few trips. Great memories. Then it broke.

And... apparently it's beyond the date to return or exchange. So, if you need a Carry On Bag to last you one or two trips, by all means, give this a go, But if you are a frequent traveler, I'd recommend looking elsewhere.

I have only used a handful of times and today it completely broke. The stitching came undone and the thin metal wire at the top broke.

After a few uses the button that turns on and off broke off not allowing me to turn on or off I returned it

It was ok at first, but it broke after maybe less than two dozen uses.  I am now looking for a new one to replace it.
