Customer Insights: Rated 4.5/5 from 397 reviews.
The lid over the drinking hole covers the rim, and this makes it healthier and more sanitary than other types of lids, which is the case with 99% of other travel mugs. Both the weight and circumference are very good--it's not too heavy when filled, and tapers down from top to bottom so my small hands can easily hold it. Many other travel mugs in this 20-ounce size are too big around.
Good alternative for getting a Yeti. I looked at yeti and didn't want to drop $40 so this one is a good alternative. The design is a little flawed with the screw top and the flip up stopper but to save $30 for basically the same thing I am happy with the purchase.
It definitely keeps beverage hot and I prefer the screw on top. This allows you to close the sip hole without the lid coming off. Definitely get your bang for your buck!
I love this cup. i have bought it 3 years ago still working good.. I lost the little flap on inside of cup that make it spill proof and had to purchase another. I love this cup.
Design and price are great. Haven't had a problem yet, use it daily. Bought extra for the office. Got three for the price of one pack of nice disposable cups. Will last a lifetime.
This travel mug is large, sturdy and at a great price. My major complaint concerns the cardboard advertising sleeve around it. It looks like it was super glued to the mug. I got the cardboard off, but can't remove the glue. Who's bright idea was that?
Everyone has their own wish list for Travel Mugs, but here's what I found on this one: Pros: * Large Capacity: 20 Oz lets me put in my 16 oz Coffee, as well as creamer, %26 still stir it. * Tapered sides allows fit into car cup holders. * Large mouth allows it to get cleaned in the dishwasher without having to set it just so. * No handle = no fussing with alignment on the lid to the handle. * Lid protects the mouth opening, or gets out of the way, with minimal nose touching. * Screw on lid Doesn't leak, when sealed properly. (Not always easy). * Well insulated = I can't tell the temp of the contents from the outside. * Textured paint on the outside makes it easier to grip. (arthritic hands = Yay) Cons: * The lid sealed like magic on day 1 = No leaks even on it's side, but by day 4, it actually leaked when I simply closed the mouth cover, without even tipping it. OK, I thought I must have been applying too much pressure to a hot liquid, so it got forced out the seal. Each successive day, I got better at not overfilling it, but also stopped relying on it not to leak, as each sip ended up with a small drip on my lower lip, or drooling down the side. I just was about to toss the lid, then decided to investigate, first. There's a small white gasket at the edge of the threads, %26 it was super smooth, except one tiny spot near the mouth hole. It had become twisted there (No idea how that happens). I got a tweezer, %26 gently slid it under, to nudge the seal back to flat. OK, Solved that problem, %26 no more leaks (today), but not knowing how it got that way will leave me untrusting of it in future. * Despite not feeling the temp on the outside of the cup, the lid must be letting the heat out, cuz the coffee inside starts dropping temp fairly soon. I get about 2 hrs of Hot to warm coffee, then it drops off to luke warm or room temp. * Lid design is mostly good, but the part where your mouth goes is pretty thick. I've had thinner travel lids, %26 to me, it's easier to drink from thinner ones. Overall, if the seal hadn't gotten twisted early on, I'd have easily given 4 stars. Just gonna take some time for me to trust it again.
I purchased one of your other cups and it's fantastic. I filled the other cup for the night. I accidentally knocked It down. I forgot about it and when I remembered it that cup also was one from Walmart it didn't have drop down the lid was still in tact and not a drop was on the floor.
It's okay but overall, a waste of money. It's top leaks and it's easy to break or crack. Mine's currently cracked and I've not dropped it on the ground or any place serious, just the sink. I can also taste metal, so I don't think this was a good buy. Spend a bit more and get a name brand.
Liked that it fits well in cup holder, color is goid too. Dislikes poor lid, leakage, rim is entirely to deep. Doesn't keep fluids/coffee hot long enough
