The cup is the best - sturdy, solid, built like a tank and very ergonomic (I have 2 of them). Unfortunately, the canteen (I also have one) is opposite - flimsy, fragile, thin wall, interior plastic lid, but at least it doesn't leak. So, a huge discrepancy between cup and canteen quality. Maybe in the future you'll make an upgraded version 2.0, something like Nalgene stainless steel (which is built like a tank too, better quality than Klean Kanteen ones). However, a big like from me because TBS is awesome!
