reduce 2.0 Tumbler with Handle - Vacuum Insulated Stainless Steel Mug Sip-It-Your-Way Lid and Straw Keeps Drinks Cold up to 34 Hours Sweat Proof, Dishwasher Safe, BPA Free (24oz, Phantom) (13228-FF)

Brought for my 3 year old and he loves it. Can be a bit stiff to undo it but ideal that he won't be able to constantly undo it! If the straw is in and its knocked it leaks a little but most cups do.Overall very happy with it.

really good idea for children, easy to convert to different styles and durable

My granddaughter loves this cup would buy again

Perfect subtitude for plastic cup and no leaking and easy to clean and use.

Loved this cup. It keeps my drink cold all day which is great as I work 12hr shifts. It fits my car holder which I was worried about as it is an American cup and this one is the new version so is slimmer at the bottom so fits great

Really a mice cup, does not tip over easily

I love my REDUCE tumbler, it's simple quirky and stable.

Expensive for the cup, it does leak, and my toddler ruined the straw by biting it so it split up the sides and is now useless, and can’t figure out how to buy replacement straws!
