Not fantastic, but they get the job done

These are all right. A few have sharp edges on the lip at first, and they aren't really "break resistant" (I dropped one half-full of water and it shattered) but they get the job done and there are a bunch of them. They did fine in my dishwasher.

they do their job.  the metal they mount to will fail before these do.

Meh. Material isn't great. But for the price, I'm ok with these.

Not exactly what I expected from the picture, but they'll work.

They do what they are supposed to do at a good price.

They look kinda of cheapy, but get the job done.

They're cheap - and that should have been my first indicator. For the price I paid, they're fine. Just don't have high expectations for a low price.

They work okay to play music (they don't stay in wonderfully well, but they're passable). Have some audio issues with the microphone when using as a Bluetooth headset to talk to people - audio goes in and out apparently (according to folks I'm talking to).

They get the job done, and were a great price.

These are pretty good for the money, not the best, not the worst but ok.

They are ok for the price, they look better than they feel.

They're about what you can expect for the price. They're not the highest quality in the world, but they're decent enough to make the purchase worth it.

They get the job done. The quality of fabric could be nicer but it's not like I'm wearing them everyday.

For the price, you really cant beat these. They get the job done.

good price, fit and finish on the bottles is not amazing (a fair amount of mold flashing on the caps and bottles) but you get what you pay for. these do the job and are cheap. If it really was a concern a razor and or sand paper would clean the bottles up to a pretty presentable state, but if thats what your after just buy nicer bottles.

These do not hold shape well but they are ok for price.

While these aren't top of the line, for the price they do the job well, and I'm quite satisfied with them.
