Universal Cup Holder by Accmor, Stroller Cup Holder, Bike Cup Holder, Large Caliber Designed Cup Holder, 360 Degrees Rotation Cup Drink Holder, Black

This works great for me. The tightening knob is a little tough for my arthitic hands, but once in place it works great. I attached it to a medical scooter (push with my good leg style) that I have to use for about eight weeks...no weight on my right leg. Im tickled that this will securely hold a big insulated cup filled with coffee! Im happy with it!

Bought two of these, one for me and one for my moms recumbent trike. The one on the trike works well as its level and it rides over bumps different than a regular bike.

I had it for a few months and unfortunately it broke

I attached the cup holder on an adult walker

I have found a workaround, but it does twist if you have a bigger than a kids water bottle in it. Mostly I wanted it for my granddaughters bottle so didnt bother me too terribly and I figured out a way when I used my bottle.

Works great on my knee scooter when you need both hands to drive.

Should be more versatile for cup size.

Product is sturdy and can be attached to my keyboard stand to hold drinks while I am playing.

I have 2 of these attached to the sides of my 14 ft aluminum fishing boat. Worked great, easy to attach, stays secure. They are at a bit of an angle due to the boat sides but take a sip of your beer before you put it in the holder and you are fine! ))

The folks that have given this item a negative review because it slips when you put a heavy bottle in it apparently cannot think abstractly. The mount turns to allow it to be mounted vertically or horizontally or anyplace in between. If you twist the mount so you can mount the holder on one of the vertical uprights then you can a brick in it and it wouldnt move. If you mount it on the horizontal cross bar, then yes a full water bottle may eventually cause the holder to slip around.
