Bests & Worsts Reviews from Amazon

I've purchased 21 of these bottles so I could have 3 shakes per day and not stress over dishes more than once per week. It worked well for a while, but the lids keep breaking. There's a fine line between not tightening them enough and having them leak everywhere when you go to shake them, or tightening them too much and causing the plastic to split at the top -in which case they leak everywhere. I know few things are made to last a lifetime, but I do take really good care of my all my things, and I am disappointed by how quickly these broke. It can also be quite inconvenient or unpleasant if you dont notice and then spill a protein shake down the front of your clothes.
