Bests & Worsts Reviews from Amazon

This mug is EXCELLENT! I can now have my tea warm for a long time! I bought this mug with autoseal, because I already owned a water bottle from Contigo with the same type of lid and it's the best I've ever had (and I've owned more than 10 water bottles, finally stuck to one now). The mug is on the tall side, which is good for cup holders. The lock feature is great for throwing it my bag pack or just when I'm carrying it around and don't want to press by accident. I got plain stainless steel due to other reviews mentioning the paint chipping on the bottom. Now to the CAREFUL part, it does keep drinks hot! So if you add boiling water to the mug for your tea, don't expect to drink from it without burning your mouth for at least an hour. I would recommend adding your hot beverage, and leaving the lid off until it's almost at drinking temperature. Yes, this will shorten from 5 to 2-3 hours of keeping your drink warm, but you won't burn your mouth. Just a tip!
