My son loves it!

Not really worth it

Do not buy it even if you see it's down to $1. It will make you extremely frustrated once you find yourself struggling to get a sip and sucking so hard and figure out how it actually works. This is completely a joke. I paid $ 15+ tax in store for this kit, but I'll be returning it. Find an alternative this is a waste.

Bought the 22oz sample pack. Never got more than 3 fills with flavor. Flavors basically all tasted similar. Terrible flavor consistency from sip to sip. Had to pull rubber plug out to get anything to flow out at all. Can't fit bottle in fridge water fill station. Basically this contraption is a money sucking flop. Cost for refills is ridiculous. Anyone that thinks this product is worth it and works well is dense. Wont continue to use.

It’s just ok it leaves an after taste.

I bought into the hype. It's okay but nothing special.

If you screw in the cartridge too tight you can't get water out of it.

Terrible product. It’s not for drinking water. One has to suck the water out. Terrible.

Thought I’d like it. But I did not. Not a bad product just not for me

Bottle Top didnt like drinking out of of it was way to small
