Ozark Trail 30 oz Slim Insulated Stainless Steel Tumbler with Straw, Double Wall Insulation Tan

I like that this tumbler is a slim 30 oz, easy to hold, no handles needed, stainless steel, BPA free, straw only, simplified and easy to clean lid, has a non slip rubber bottom, and it's a color I like. The soft, matte, medium sage green is lovely! The price and quality of Ozark Trail beat out other competitors in the store. I also bought a 40 oz tan tumbler with handle in the same brand. The only thing I'm not liking on the 30 oz slim tumbler is that it picks up a ring of dirt from my car cup holders, (but I do have a 17.5 year old vehicle so that area is not as clean as it used to be). I have wiped down the outside of the tumbler with an antibacterial wipe and that helps get it off. What I love about both the 30 oz %26 40 oz tumblers is that the lids are simply constructed (no flip or slide openings or carry handles), straw based (no sip option unless you open the lid to drink from the cup), they screw on and are very easy to disassemble and clean (to keep mold from forming). I am handwashing them for now to preserve newness. Both tumblers keep drinks cold as advertised. Some people look for how spill proof tumblers are. If the 30 oz is tipped on its side briefly, it seems to not spill because of the screw type lid, but if it is left like that or turned upside down the liquid will dribble out the straw or straw area. I'm not in the habit of spilling my drinks, nor am I using them for camping purposes, so that wasn't high on my priority list. I have not tested the 40 oz for spilling or leaking, but I'm thinking the 40 oz might even prove to be better in that area.
