Very flimsy. Had to put rubber bands around the bottom to keep it from moving around while inside my car cup holder ### ⭐⭐⭐ I also realize this really works best as a way to hold standard size coffee mugs *by S***M on Reviewed in the United States on April 14, 2017* Now that I have it in hand, I realize there really isn't much to it.  I also realize this really works best as a way to hold standard size coffee mugs, as it's not nearly heavy enough to securely hold anything much taller.The plastic is a little less than a 1/4 inch thick.   The bottom diameter is just shy of 2 and 1/2 inches wide and two inches deep.  The top is roughly 3 and 3/4 inch in diameter and 3 inches deep. The bottom is hollow which is unfortunate because I feel if it was weighted it would stay in place a lot better.  All together,  I can't imagine this thing weighs more than a couple ounces. With a filled McDonalds cup inside it, the drinks weight causes the lightweight unit to lift when making sudden stops. In the picture I provided, you can see where the bottom pulls up in the back as the weight of the cup forces it out.  I'm hoping this won't be an issue with the larger diameter cups I get from places like IN and OUT though since they may fit more snugly in the unit and are otherwise too wide to fit in the cup holders of my 2002 Accent.  Sadly, my cat mug won't fit but I have some more standard size coffee mugs that do.   My contigo thermos also fits, but it suffers from the same issue as the mcdonalds cup. I think the manufacturer could improve this by adding two things: a weighted bottom and rubberized or foam sides to allow for a more secure and snug fit inside your cars cup holder.   I'm going to try to add these things myself and will report back in 2099 after I've finished  all the other extraneous tasks on my list. ### ⭐⭐⭐⭐⭐ Works great. *by G***. on Reviewed in the United States on April 13, 2022* I have an older ('97) vehicle, built before insulated travel cups were a thing. The cup holders are shallow and small diameter. This adapter works great. I wrapped around the bottom with a folded paper towel to snug up the fit, and now I can use my 30oz YETI or my 1000ml CamelBak. Simple, effective, and made in the USA.
