Review on Glacier 40 oz Stainless Steel Tumbler Mug with Handle - Dishwasher Safe, BPA Free - Sweat Proof, Keeps Drinks Cold up to 34 Hours - Opaque Gloss Finish by Uriel Arocha

Excellent product. This mug was everything it claimed to be. Its insulating properties are excellent and it keeps drinks as cold as iced tea with ice for over 24 hours and hot drinks warm and drinkable for up to 8 hours. The lid closes very tightly, preventing drinks from spilling or being contaminated with dust and other airborne contaminants such as wood shavings in my shop, blown leaves, etc. I have now purchased two of these mugs and will not hesitate to purchase more as gifts. , or for my personal use.
