"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!"

These tumblers are AWESOME! Such

"These tumblers are AWESOME! Such good quality, love the dedicated spot for the lid under the cup, & great options as well."

"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."

Worse

"My shipment just been lost and delayed worst experience. Till now 8 days still no cup no update on shipment VSSL cup was at my door in 4 days. If you don't mind waiting like it's 1970 for your order then order away if not there other better cups that will be delivered in a more timely manner especially if we the customer are paying for shipping and handling. Feels like I just been ripped off cause now no one knows where the order is at. Contacted DHL and USPS no one knows."

Very nice and cold

"very nice and keeps things very cold but the bottom doesn't screw in and falls out. It works great but one little change would allow the lid from not falling out on the bottom"

One more thing. . . . .

"I love this item on all accounts EXCEPT. . . . . the build is excellent, the colors are perfect and look nice in and understated way, the lids and the magnetic keep is a best in class, however the cup design is such that is does not fit into all cup holders. So the only thing I would change is the out diameter of the cup."

— MATTHEW R. (4/5)

"So far so good. Love the durability of the cup and it still fits in my vehicle cup holders which is a win. I like that I don’t have to worry about tipping it over or it spilling. The design is holding up flawlessly thus far. I have had it only 1 day but I can see this being my go to tumbler for years to come"

— SETH (5/5)

"These were at first superb items. They did an and still do, do an excellent job of insulating and keeping things cold or hot for an extended period of time. However, just had to take the silicone seals off one of my tumblers cuz it was getting mold behind it. Not a large issue in and of itself. What is to me an issue is the fact the seals are a split design that are extremely hard to clean. See the attached photo. Otherwise they are a great item. Why the seal is a split design is beyond me."
