Very sturdy and leak-proof
This product has been one of my favorite purchases in recent memory. I commute via public transportation a lot so I needed a shaker bottle that could store my pre-workout and whey protein but could also just be thrown into my gym bag without me worrying about leaks. I fill up each side of the bottle with the powders before I leave home for the day and then add water and mix when I'm leaving from work/school to go to the gym. Even after a few weeks of use, I still haven't had issues with powder OR liquid leaking. Dropped a full bottle once on the cement floor while walking and the thing held up like a champ. I actually ended up buying 2 more bottles so that I have some spares in case I don't have time for cleaning/drying/re-filling. As others have mentioned, I'm concerned that the snaps on the lid may end up wearing down over time and break (it's not really a hinge-type system but feels more like bending plastic into place). But, hopefully with a few of these bottles in rotation that will be a long way away - if it ever does happen. I thought about using one of those container-type bottles that holds powder in a compartment instead of this system but if I can avoid an extra item/piece to wash and worry about, that makes my life easier and I'm much happier because of it.
