    These tumblers are Great ! I have 6 of them now, LOL. They work soo well, absolutly love them, use them everyday. My first one was a gift from one of my vendors at work, and I loved it soo much, I ordered another one, then another, and so on. I have even given them as gifts. I use them everyday and they keep my drinks hot ! The quality is exceptional, the price point is way too low for the quality of the product, so do not let the reasonable price fool you, these things are phenominal. The bottom and base are free of coatings so that they are easy to clean and less likely to get dinged or chipped on the heavy wear areas like some of the competitors. alot of attention to detail on all of their products. Wish stores would carry these locally. The interiors dont even stain like the competition, must be a higher grade of stainless steel. whatever they are doing they are doing a fantastic job on both these tumblers and their coolers. I have both the all stainless versions and numerous colors and they have all held up to daily use and abuse. The lids are readily available and inexpensive to replace, simple and easy to clean, Just the whole thing is well thought out. GET ONE, or a few !!
