Caffeine Beaker Mug, Caffeine Molecule Mug - Chemistry Mug 16 oz Borosilicate Glass Coffee Mugs with Handle and Measuring for Coffee, Latte, Tea or Hot and Cold Beverage, Tea Coffee Mug by Amugo

I got this for a nerdy friend of mine....he loves it! He was even joking that he doesn't need to buy measuring cups since it comes with the ml on the side.

Great idea for a mug, loved it when it arrived ....only to find the decals came off after a few washes leaving us with a plain glass. Terrible : disappointed beyond measure.

I wanted a mug that would hold a full 20oz. when filled to the brim, and this "16 oz. mug does exactly that. The other key thing for me is that I wanted a mug that would be my daily "desk mug" so I could make my morning latte and have it on my beverage warmer at my desk and sip it over the course of several hours. If you have a beverage/mug warmer, you know that the key to those working well is that the mug you use needs to be flat or nearly flat on the bottom. Most mugs are not flat - they have a "ring" or "rim" around them and thus aren't flat when placed on a warmer. This mug is exactly that. I bought mine exactly FOUR YEARS AGO and have used it every single workday since! At first I was very concerned at the thin glass. But it has lasted this entire time. I hand wash it - no dishwasher. I do use it in the microwave every day to heat up the milk for my latte, and I also use a milk frother wisk to blend in my protein powder. So this thing has held up perfectly, despite how thin the material is. For my purposes this has been absolutely perfect! If I am looking for a mug to sit with on the couch or take out on the porch with me that will keep the beverage hot for a long time, this is not the mug I use for that. But at the desk and on a beverage warmer it is absolutely perfect. And the handle is also a very nice size and VERY sturdy.

Le encantó a mi esposa y resiste bien

Nice borosilicate cup/mug and as expected very thin glass and almost weightless, but delicate and not for people with big fingers. Update: I used this cup 4 times and was very careful with it and I just noticed it was leaking out the bottom. Coffee kept showing up on the countertop and after transferring to another cup I turned the is cup over and sure enough a small crack. This is absurd! I will attempt to get a refund.
