Be Warned - the Matte Black scratches easily.... VERY EASILY
on September 7, 2016
My first use of this tumbler, I had it on the ground underneath a table. At one point I accidentally knocked it over and within 4 seconds of being on the ground, it received an insane amount of scratches. It looks like I've had it for 10 years, but I've used it once. I have cheap promo Tumblers that I allow to get banged around because they were free and they don't look half as bad as this Tumbler.
This simply is not worth the investment. There are better tumblers out there that are more resilient, keep beverages hot/cold for longer periods, cost less, and have a much simpler yet still effective open/close mechanism (the one on here is over complicated and not convenient when driving). Save your money.
Also, I found this Tumbler for less money in a department store... but it was still more expensive there than better alternatives.
