Love it death but recently discovered that when you remove the rubber mouthpiece you might discover some built up crud...make sure you wash there. My water filter attachment fits perfectly when backpacking. I always carry one with me everywhere and they are extremely durable. The only other drawback is I can never get that last bit of water out without taking off the lid...the straw doesn't reach the bottom.
