Hydro Cup - Car Cup Holder Adapter for Hydro Flasks (32/40 Ounce), Nalgenes (32/48 Ounce), Yeti Ramblers (36 Ounce), Klean Kanteens (32/40 Ounce), and Other Large Bottles

I use this for my large, 40oz insulated, water bottle and it is really great. The only downside is the diameter of my bottle is so large that the adapter gets stuck on the bottle and comes out when I lift the bottle up. It isn't a problem with the product, I'm just pushing the maximum capacity of it. I've fixed this by placing something in the bottom of the adapter to act as a lifter/spacer so that my bottle doesn't sit so low in the adapter. It is still very stable, doesn't tip or fall out, and my bottle lifts out with no problems!

I had a short Stanley cup with a handle and it would get stuck in the cup holder made in the car. This one was too tall but I was able to cut it down to work and now it is easier to raise the cup out of the holder.

Of course this is huge — it has to hold a 32 ounce bottle. It’s too big for my Mini Cooper (no surprise, really). It doesn’t fit in the driver’s side cupholder at all. It sort of fits in the passenger side cupholder, at an angle, but it’s usable with the Arca bottle. I wouldn’t try it with an open cup. If the real estate on your vehicle’s console is tight, you might want to measure before ordering this cupholder, and consider whether it would be blocking any important knobs, buttons, or gauges. The cupholder itself is a fine product. The plastic seems sturdy, it fits the 32 oz bottle. It’s just not meant for those of us whose cars fall somewhere between “subcompact” and “Matchbox.” (I do love my Mini, but like all of us, it has its flaws.)

I purchased my first one for my 14 Ford truck. It fits in all the cup holders, but I specifically bought it for my hydro flask to put in the front floor (slide-out) cup holders. Works great! I bought my second one for my 16 Audi A4 (anyone who owns an Audi knows they suck in the cup holder department). I was worried it would be top-heavy, but it works great. I will absolutely buy again.

I got this for my 2016 crosstrek to hold my 32oz hydroflask. it holds the hydroflask really well, unfortunately the bottom is too short for the cupholders in my car, so the whole thing wobbles if there's a bottle in it. I haven't tried it yet, but I'm hoping to get a tall plastic dollar store cup to put it in so it will stop wobbling.

I like it. I appreciate that it fits my thermal water cup and my cup doesn't go flying across my car when making a turn anymore. Fits tall cups with wide brims easily

I also bought the cactus rubber protector and having this on the water bottle while using the cup holder, the bottle won't freeze easily. Very cheap.

Works as it should with 40oz hydroflask. Stays in the cup holder and is plenty big enough for the flask. Not sure about long term durability as I just got it but I would imagine that it will be just fine as long as I don't treat it as though it is made of titanium (it is plastic and we all know that plastic will break if you try hard enough).
