"Disappointed with this product. I bought a plastic one for my son to use at school and it works great. However, the stainless one I bought for myself leaks all over the place. I bought it to take in the car - just toss it on the seat; throw it in a day pack for a hike, etc. Works awesome if you don't put it on it's side. Works fine for a "leave it on my desk" situation, but not if you're on the go.
I got a replacement from eBags (who are always awesome to work with!) and the second one leaked too."
