I use a normal water bottle and I shake it.
Fucking magic.
Some cool designs though, probably overall useless but neat none the less.
No funnel involved with these type, kinda handy.
@Op though, Smart shake lids / that style of lid break within a couple weeks 90% of the time, but sometimes you get one that doesn't give out. Worth it at that price imo.
