If a business offered you basically the same product with one costing $40 and the other costing less than $10...which one would you buy? Not sure about you, but I'm going to save some money! The Ozark Trail 30-oz, Double- Walled, Vacuum- Sealed Tumbler is every bit as functional as the "name brand" $40 option on the market. I purchased two of these online for $9.74 each and had them shipped site-to-store ( because my local store is always sold out....good indication, right?). My wife and I love these and have used them daily since they arrived. I haven't put hot liquid in them, but they do stay cold all day. I would suggest personalizing your cup to make it easily recognizable at home or in public. I purchased a vehicle decal for my cup since they are made to be on vehicles out in the elements. I haven't had any issues with the decal peeling due to washing the cup. If you're willing to pay $40 for a cup...you might as well buy 4 of the Ozark Trail tumblers. You won't be disappointed!
