Alpha Armur 20/30/36 Oz Tumbler Double Wall Vacuum Insulated Stainless Steel Tumbler /Hydro Travel Mug Stainless Steel Water Bottle 12 Oz Stainless Steel Can Insulator Can Cooler

I bought this tumbler because I wanted to take it on a vacation and didn't want to take and potentially damage my Yeti 20 oz. For $5, it was a harmless purchase. On vacation, in ridiculous tropical weather, this tumbler did quite reasonably, so I decided to put it head to head to my Yeti 20 oz/ This was an unscientific study. I used approximately the same amount of ice and water in both and let them sit in my office for 17 hours. As you can see from the pictures, both tumblers ave about the same amount of ice and water. I didn't measure the temp but there's no perceptible difference, certainly not anything to justify the dramatic difference in price. You can see in the pictures they look about the same, have about the same amount of ice to start, and about the same amount of ice compared to each other 17 hours later.I can't speak for the other sizes/shapes, but if you're in the market for a 20 oz tumbler, this one works about as well as the similar Yeti product. Note is that the diameters of the lids are not the same, so you cannot swap Yeti tumbler accessories with this one.Also, yes the sticker is hard to remove, but I got it off eventually with some patience and hot water.

The tumbler is great at keeping things hot. My coffee stays hot for about 3 - 4 hours. About a week after I got it though I started to see a small fracture in the lid. I have been very careful with it and never put it in the dishwasher. Only hand washing. It has slowly continued to fracture although it hasn't leaked as of yet. I have not tried it yet with anything cold. I'm sure it would be great for that though...EDIT: The crack in the lid has run completely across the top now. The tumbler itself is awesome. The lid though is another thing. -Another star.

Very nicely made and fits into my car cup holder easily. Keeps my iced tea very cold most of the day! The only issue preventing a 5th star is that the sipping hole does not have a cover so it's always open and will spill the contents if it tips over. Nice cup for the price.

Comes with annoying sticker applied directly to the metal. I spent 15 minutes trying to remove it and now my mug is all scratched up. Why would you put a sticker directly on the product. Put it on the plastic that was packaged in

The Alpha Armur stickers are a pain to get off. I mean, I almost threw the 3 cups away that I bought. I have no idea why the company would put stickers like that on the product. A cup is hard to screw up but there is a first time for everything. Take a lesson from YETI and just put a wrap on the cups that comes easily off. I wont be buying this product anytime soon until this issue is fixed. I'm sure I am not alone in this issue. they need to revisit this issue with their manufacturer.If you want to spend 30 minutes per cup taking off the stickers then this cup is for you.

The cup works how it was advertised. However, the label glue is a little aggressive and does not come off cleanly.

Works really well. I love this cup but WHY does the company use a sticker that takes forever to peel off?!

The cup is great but the lid was cracked upon arrival
