Reviewed by Tim (Uckfield Millets) - 8th Apr, 2017Staff reviewAmazing mug!I love this mug, have two myself. Sold many of these and had nothing but good comments about them. The one design issue with them is a small tab that restricts how far the flip top goes back, you can easily carve this off which makes it the best thermal mug we do. I quite often carry it full in my pocket with no concern over leakage and likewise when I am driving and it falls over I don't feel the need to pull over and rescue it. The only complaint I've ever had from a customer was that after three hours his coffee was still too hot to drink!
