Have had for about 4 months, and the straps are a bit tricky to adjust, and one has the stitching getting loose, but other than that it's working as needed

The lock on the clip fails after a few months.  Then, you have to be sure that the opening is up.  That is, you cannot attach it sideways to strap anymore.

the rubber strap for my suunto core started to tear after about 1.5 years of daily use.  i decided to replace it with this leather one, thinking it would be more durable.  i have owned the new strap for 1 month, and already the leather is starting to delaminate from itself, like on a cheap belt.  also, when i got it, the screws that it came with unscrewed (possibly because i didn't tighten them enough, or use loc-tite).  i re-installed new screws with loc-tite and they've held fast for about week now.  i can't imagine this crappy leather is going to last more than another 6 months before it looks like crap and needs replacement.  i do take it in the shower every day, but i assumed that would be fine, since it's a suunto and is meant to be badass.

The straps have a tendency to slip when weight is added (using on a hammock). I had to tie off the loose end of the strap to keep it from loosening over night

I am just starting to use these and they take some getting used to.  I do not use them every time I work out.  The strap is sturdy.  I think it may just take some time for me to figure it out.

The straps are very difficult to adjust.  I require a very long strap and I simply can't get the length because of the plastic, which just doesn't want to pull through the brackets.  I've ordered some new ones so hopefully this problem is solved. Overall, this is the best solution for a backless bra. There seems to have a slight slimming and smooth look.  Anything is better than the stick-on cups, which fell off half way through an evening. The thong part is comfortable enough.

I've had this for 8-9 months now. Due to the size, it occasionally gets caught on something, so the belt loops seem to be stretching a bit. I expect them to rip off at some point.

At first I was happy with my purchase of the handsfree bra, but four months later I am not.  The Velcro has worn out on the strap so it doesn't even stay on.  Since most women breastfeed for 6 months to a year I would expect it to have at least lasted 6 months.

It's helping my back however, the Velcro strap is already becoming detached from the belt and its in an area where it doesn't even strap. I've only wore it 4 times.

this backpack has fallen apart after only 4 months of intermittent use. the shoulder straps are ripped out, not through effort but shoddy construction. i can see other places, not even stress points, where the sewing is loose and looks like it needs to be fixed. for as much as this cost and as long as we had to wait for it to arrive from China/Asia. I am seriously irritated that it hasn't lasted more than a couple of months. luckily i sew fairly well and can likely fix/shore up the problem areas.

Seat cushion itself is wonderful, it's the straps that hold the seat cushion in position that are terrible. The threading that hold the straps to the seat cushion itself break loose rather easy. I bought wider and stronger elastic strapping from a fabric store attached the strapping to the seat cushion with regular thread then took the cushion to a shoe cobbler and had him sew the straps again. Straps have been holding so far. This was done approx. 2 months ago and are holding firm on my truck seat. This info should be passed back to the manufacture of the seat, but I would think I'm not the 1st one to complain about this.

can't believe a strap of this quality is so inexpensive

I purchased this Fanny Pack for travel and later ended up using it 4 to 5 days a week for work.  The weird factory smell wore off after a month or so.  I'm disappointed that it only lasted about 4 months before the stitching on the straps began to fall apart.  Also, the straps don't really stay in place and the fanny pack never stayed as tight on my waist as i wanted it to.  I love the look, feel and design but they really need to improve the straps! I would pay extra for straps that weren't cheaply made.

The straps on this bag are the major positive, they:
1. Provide a more secure closure to the packs than the 2x similar Iberia top tube packs; that I own.
2. Allow the pack to be expanded and contracted as necessary
3. Make it less likely you will hit the pack with your knees while standing up in that saddle.
4. Keep the bags closed when the bike is turned over to replace flat tires.

 The main negative is that one of the seams has failed after only 6+ months of riding, this was slightly expected due to the Manufactured in China sticker and low price.

This backpack has suited me well for around 4-5 months, but I am afraid that is all the lifespan that it has as it has started to show bad signs of wear. The left shoulder strap stitching is coming apart and revealing the bubble wrap material used for the inside. Like some other reviews, the zippers are getting really difficult to close at the top of the backpack now, I often have to use one zipper to go all the way around the backpack instead of meeting the two zippers at the top. I am a pretty heavy commuter, I take this thing on a 4 mile push scooter ride in SF every weekday, but I expected it to last longer than it did. 3 Stars because it worked great for only 4 or so months.
