I bought this set and shortly after found them for $1.50 at Walmart. I used them so I wasn't upset. After three days later one cracked while I was drinking it, which caused a leak. I just was drinking water and the second bottle cracked as well. This was a waste of my money.

I had one of these a couple of years ago which lasted about 2 years and was great, I only replaced it last year because I thought it was getting a bit old and I wanted to get my boyfriend one so I got the two pack so we could both have new ones. The ones I got last year lasted only a couple of months and then disappointingly started leaking so I had to throw them out. I really missed having one so I got two more last month for us and mine only lasted a few days before leaking again and my boyfriend's lasted less than a week and a half. I really want these water bottles because they're the only ones we can find that hold a large amount of water that we don't have to refill often but they've been very disappointing after working perfectly before.

just right

Perfect for water on a private island where we have to haul it from one source back to the house, these are getting hard to find in retail stores, than goodness for Amazon

This bottle is not Bulletproof by any means, I have several in some of them do leak after just a few weeks, I guess it's a good thing they are fairly cheap
