Your best yet! Now make wine glasses.
Really enjoying the new trueenamel tumbler, has a very slick finish and is easy to clean. Only negative so far is the gasket should have been designed slightly thicker as it pops out a little too easily as the finish is so smooth on the interior.
Nice mug, but don't see the value in the enamel coated mug versus the non-coated. Coated just feels more fragile with little positive trade off. Assuming you're 'on the go' if you're buying a tumbler. This enamel doesn't feel like it will stand up to a mobile lifestyle.
Beautiful tumbler but a bit fragile.
Love the feel and look of the TruEnamel Tumbler, however it seems the enamel is a bit fragile. I noticed a small chip in the bottom and I did not drop it and don’t remember bumping it hard. Love the idea but the execution needs some work. I am a big fan of all the other Miir products I have purchased.
Best Tumbler in the market
Whoever pitched adding enamel to an insulated tumbler deserves a big award. Nothing compares to the smoothness of enamel when you take a sip; its neutral flavour helps preserve the drink's quality. TruEnamel is a game-changer for reusable cups. I hope soon we get more options for sizes.
