Wish the lid had a no hole version.If you plan to get this, make sure to use soap and warm water and wash the inside with a sponge prior to 1st use, otherwise it'll taste weird. I only did a cold rinse and regret not going the full mile.Other than that, it works nicely. It's not that grippy outside so be careful. Still better than glass or ceramic mug though.Another thing I wish it had was a rubber ring at the bottom so it can stay on the surface better in one spot... but hey, I got what I paid for. Can't compare a higher priced item's features and expect that much from a low priced one.When I put milk in it and drink it immediately after, it definitely feels slightly colder than if I repeated the scenario with a ceramic mug. I prefer cold drinks so that's a benefit. It's very small difference, most will probably not notice though.Would I buy again if I went back in time? I guess I would. I still would've preferred a lid without the hole though.
