GOOD VALUE GOR PRICE BUT WATCH THE LID CAREFULLY!

The cup is very well insulated and the surface texture allows easy gripping even when the handle isn't in use. The reason why I rated the lid lower is the center swivel was broken when it was delivered and I didn't have the time option for a return as I needed an emergency use mug. 🙀
