Worth it!!!

The lid turns and is secure, it does NOT leak. Fits in a cup holder, it's about the size of a medium coffee cup. When I used it for Ice water, it sweats a LOT but putting a paper towel under it was okay.

Basic, multiple. And great price.

Overall these to go cups have been great. In my set there was 1 lid that was causing spilling when taking a sip so I had to throw that one away. If u need just a plain 2 go cup and u want a set of them , one for everyday of the week and at a great price? You should definitely purchase these. I highly recommend them!!!!
