now my drink stays cold

Great

Great Tumbler

Keeps drink cold!

EXCELLENT CUPS

Lids came in cracked

We were searching for a larger, insulated mug for a while before coming across this item. Something to upgrade the metal tumblers we'd been using but refilling too often. This mug at 50oz fixed that! Lots of pluses beyond that, though. The tapered bottom fits both the large and small cup holders in my Hyundai. The inner measurement markings aren't much use to me but are nice to have I guess. I thought the handle might be burden and kinda hoped it was removable, but it's turned out to be a non-removeable blessing, very durable and functional. Speaking of durable, the included straw is nice and solid with a larger diameter than most drinking straws. The bottom's rubbery grip is great, and I haven't seen the thing sweat a drop. I didn't clumsily knock it off the table this week-- no leaking, no dent! I've seen a couple concerns about the thermal time, but haven't had an issue with that. My water stayed cold, ice didn't seem to melt much water being in the car for several hours on a 100° day. It's held over overnight as well. Can't really confirm or deny the 50 hour claim as drinks don't last that long with me. But I can say at $15 a mug, both me and my girlfriend feel like this was a helluva deal!!!

Just bought these and they DO NOT keep liquids cold. I filled with ice and then topped with water. Within 3 hours, there was no ice left, water was room temp. Thought weird, so I tried again the next day. The cold was coming right through the outside of the cup, and the ice melted quickly. No insulation. Will be returning.

I used to buy 44 ounce styrofoam cups but have switched to these ginormous things. They are big, heavy, and just barely fit in my car cup holder, and were too for my school bus cup holder, but I've made it work by hooking the handle on something. So why the 5 star rating? My husband made me ice tea yesterday morning at 5:45 am, and when I finished late this afternoon, there were still 3 ice cubes left. I swear this holds my tea colder and longer than is possible by physical law. We have had 80s and 90s degree weather and it's stays cold all day and into the night.

The older version of these without the handles or colors were MUCH better. The handles get in the way, are not removable, and they changed the design of the bottom so that they are less stable. The old ones had flat bottoms without the bevel. They were also just plain stainless, so no paint to chip. Unfortunately it seems that Reduce doesn't make the old ones any more, only these. Buy the old ones without the handle if you can find them at a decent price......
