Sumyth 8 Pack-Kitchen Shears

This is not a review of how well it keeps things cold since that was not the purpose. This is based on how hot coffee is kept. Heated up the inside with hot water to warm it first. Put in hot coffee, put it on the counter. About 1.5 hours it was tepid at best. My little Wal-mart one keeps things hotter than this thing. Then there is the issue of the lid. The heat made the rubber pliable so it did not actually seat securely, it moved around. That in turn created some type of suction that if you have arthritis in your hands as I do, good luck trying to get the lid off.All in all, it went back and I will stick with my little Wal-mart puppy that at hour 6 it is at the tepid point.

I've been on a mission this fall to get a boat load (well, at least 20) and whenever I see a 30 oz tumbler at a reasonable price I pounce. Budget and/or finding them on ab associated discount site prevents me from buying them all at once. I've gotten several different brands over the last few month and while some vary about how many hrs things stay hot or cold, they have all stayed cold longer than 24 hours and hot 4-6 hrs.This one is no exception.So 5 stars. Everyone on my Christmas list is going to love these.

Living in Arizona,especially in the summer, it is so nice to have something keep your drink cold for a long time. I decided to try putting my morning coffee in there and usually I get busy with work and end up reheating it a few times with regular coffee mugs and With the thermonator it was so nice to have my coffee warm still a few hours later!

I love the 30 ounce size. The Thermonator fits perfectly in the cupholder in my vehicle without rattling around. I slide a disposable straw through the hole and it works perfectly for me. I left it full of ice water in my car during an appointment this morning in Arizona and was thrilled to find it still full of ice in our Arizona heat 4 hours later! Great product!!!

I bought this one because I my husband claimed the first one I ordered. My son has now claimed the second one I ordered. Maybe the third time will be the charm, and I'll get to keep my cup for more than a day or two?

so I bought this gem in May. Today my father in law saw me sipping water out of this throughout this hot Phoenix day. Yes, I failed to buy one for him for Father's Day thinking he would not appreciate the value of this amazing product, I was wrong. He asked me if I would give it to him for his long haul back to Indiana. I hesitated. My husband held his breath as he knows how I cherish my cup. I relented. I figured I would replace it and I wanted my father in law to stay hydrated. Apparently there is someone I love just a hair more than my thermometer. A hair more.

This cup is awesome! Keeps my cold drinks cold for a looooong time. I kept it on my nightstand full of ice and water and the next day the ice was still there and my water was still cold. I like to drink through a straw and you can fit one through the slot. Great product!

A great morning mug with excellent insulation. A little big for some cup holders.
