Review on Zak Designs Leak Proof Plastic Polypropylene by Michael Maes

I have another Zach! Signature mug which was great. This one, not so much. After the second wash, the pattern was more than half gone. The locking mechanism is broken. This is my car mug for a 4 year old so it couldn't be dropped from the outside. The mug is a great size for your hands. If lock and design issues aren't a big deal to you, you'll love this mug. I'm just upset because I paid for a decent mug and it didn't last long.
