Poor quality strap joints.

When I received the watch, the top strap had come off. I tried to fit it back, but it is so loose it won't fit. I returned the watch and Amazon promptly refunded. However, it is a shame I had to return this watch. I really liked the white dial with blue needles.

The top strap broke less than two months after we bought it.  JanSport is usually very high quality so I don't mind the high prices.  This one didn't meet that standard.

This is an update.  After 4 uses, one of the two I kept has already come apart.  The black strap came out of the sewn seam.  The quality of these chairs is very poor.  The stitching is very weak.  I wish I had sent them all back.  I suggest avoiding this product.

I was expecting a more structured "chair".  In a relaxed position, you will be reclining.  Sitting and staying upright takes effort.  There is very little back support and the black adjustable straps are irritating on your arms.  I ordered 4.  I had to return 2 as the fabric was ripped.

Straps are good quality, but the rubber handles on the metal ratchets continue to fall off.

I was very disappointed with the quality of this product two out of four of the elastic straps broke as I attempted to put it on. Very poor stitching. As I went to return and get another the price had increased. I contacted the seller but never heard back.

Strap doesn't fit through hole on the one I received. Then the whole assembly fell apart when I tried to pull it through with pliers. Very poorly designed and cheap.

I should have listened to others' detailed criticisms.

Glued straps = stiff straps
Poorly machined clasps = offset holes, zero hold
Spring bars as part of clasp = what were they thinking?

As others have stated, and they're correct, the whole purpose of a NATO strap is to prevent the loss of a watch should one of its lug spring bars fails. Here, with this poorly designed and executed strap, the single point of failure is the strap itself. The clasp broke the very first time I was putting the watch on my wrist. Thankfully I was seated, or my ~$800 watch would have taken a fall thanks to this sub-$20 strap.

I'm sticking with Wrist Candy Watch Club straps from now on.

I have a pair of these that are 4 years old that are in better shape than the new pair I just wore 3 times. The picture looks identical to the old pair, but the quality is not there.  I was astonished when the strap on one shoe fell off.  The stitching is poor.  My old pair are and always were  comfortable and still look good.  This new pair is not comfortable and now need repair.  They do not have the look of quality that my old pair have.  I would return these if I could.

I bought these for a family photo shoot. The metal hook for the strap broke apart the morning we put them on for the shoot. Very poor quality. Sadly the return window is expired, and these aren't wearable

The shoulder strap popped apart after a short period of time. I had to use gorilla glue to get it to remain intact.

Nice look.  Very fragile. The elastic connection on the strap failed on both shoes almost simultaneously, and after only 6 or 7 wearings.  This is disappointing, because they were comfortable, and I liked the way they looked.  Very poor construction on the strap.
