Hydra Cup [6 Pack] ProStand Funnel Set w/Stand for Filling Water Bottles, Shaker Bottles w/Protein Powder, Supplement Storage Set, Take to Go or Kitchen Use, Keychain for Shaker Cup, BPA Free

These are really convenient when you’re constantly on the go. I love them. They’re the perfect size for my drinks. I would put pre workout and protein in them and they wouldn’t leak at all. I would hook it right onto my backpack

These are great for taking protein powder or supplements on the go. It makes getting things into a bottle with a smaller opening so much easier.

Easy and convenient supplement transportation

These worked great for dividing my protein up into days for a trip but I can't use one of them because I (like others I have seen in reviews) didn't get the little black lid. So much easier to transfer into a water bottle or shaker than using little ziplocks! Bulkier yes, but easier to use.

I love these things, ontop of ease of use for getting some pre/protien i use them as a great way to hole some meal replacement shakes when backpacking 10/10 worth the cash

These work great and being able to stand makes them very easy to fill

I've had no issues with these. I use them for protein powder/pre workout. Makes it easy to be sure I've got what I need when I can't make it from home. I usually just pre portion what I need per funnel then I can put it in my bag for later. Weather you're pouring into a shaker or directly into a water bottle, they work no problem.

I've ordered these cups four times now. The reason is that the small caps keep cracking, which makes the powder leak all over. I'm not sure what the design issue is with the small caps, but I'd love if they would offer replacement caps. The funnel itself and the large caps are fine. It's just the small ones that keep cracking, rendering the entire product completely useless.
