Great canteens for the money!
The strapping on mine out of the bag was fresh and strong, had no problems sticking it on a belt to wander around with. Cup is held on securely and came dusty by in good shape. Under-rated how useful a small cup can be.
Insulation was intact and works quite well at keeping water cold. Canteen is also bouyant which is nice if you are filling up from a natural source for purifying or boating.
Plastic canteen itself has a bit of a smell to it. I did my usual mild bleach solution - rinse - baking soda - rinse clean out and it got the bulk of it out. Based on the age of the plastic I would not put hot drinks in them. BPAs not a huge concern as I tend to drink and replenish relatively quickly.
Overall, a great buy and I am highly considering another pair so I can keep one with pretty much every backpack I own. More water on the person is never a bad thing.
