Novel design, one point to consider

"I've been searching for a new tumbler design that was leakproof, but still enabled sipping and was at least 16 oz - I'd say this definitely fits the bill! The colors are great, the quality seems top-notch, and I appreciate the novel design. The only reason for 4/5 stars instead of 5/5 is that while the magnetic lid fitting on the bottom is sleek, the bottom of the cup will touch every surface you rest your cup on, and that means the inside of the top does too when it's stored under the cup. Then when you put that piece back on top, it touches where you put your mouth. Not a deal breaker for me (it's good for the immune system), but just something to consider."

Fantastic Tumbler

"I've had many tumblers that I've used primarily for coffee, but this by far is the absolute best I've had. It is exactly what you want it to be. I'd give it more stars if I could. SMMT knows what's up"

— Dom R. (5/5)

"It’s a nice product, but when I think of the total cost plus shipping it’s a little pricey for the size and limited function. There’s not even a way to add a strap or hook if you need to attach it to something. Don’t get me wrong, it works well and keeps your temperatures sustained for extended periods of time, I just think you can get a lot more for less somewhere else."

"It’s a little to small for me. It would have been nice if it held one can of soda and ice . The magnet on the bottom seems to be pretty good, however the lid is always getting stuck on it. It’s ok at best . I was really looking forward to this tumbler"

Just what I wanted

"I love this tumbler. I like drinking my beverages hot, but ride a bike or a bus to work. This tumbler allows me to brew my tea or coffee at home, chuck it bag, and drink it piping hot at work. The mouth is wide enough to fit a tea steeper, and the inner sip lid allows for nice big sips that don’t immediately scald your mouth, unlike other packable flasks. Precisely the product I’ve been waiting for!"

"Magnet in the lid broke first fall from the counter top.. it still functions at 50% . But now it rattles and is super annoying. Also the rubber bushing between the top comes off all the time"

Best of the Best

Difficult Opening Lid

"Having difficulty with lid opening, otherwise enthusiasm for using tumbler. Can SMMT outdoors include manual instructions for proper use in opening tumbler, senior citizen. Thank you."

"Really interesting tumbler… it took us a couple minutes to wrap our heads around the lid system but when you get it, it’s amazing. It creates such a great seal, don’t twist it too tight - it doesn’t need it like other lids…. The self contained coaster is great and it keeps things hot OR cold for hours and hours. I would have given it five stars but I’m trying to cut out plastics… if it had less plastic, I’d definitely say it’s perfect."
