Pack of 2 Stroller Cup Holders, Universal Drinks Holder for Bikes, Trolleys or Walkers (2 Pack)

1 fell off boat already they are cheap but it is as described works!

Great product. Highly recommend.

My Weldcraft boat has a round handle on the passenger side of the dash, this unit is capable of clamping onto that bar and able to hold my 22oz. HydroFlask coffee mug without it moving around too much, as well as standard plastic water bottles. It could be a bit stronger in the clamping department, but I cant complain too much since it really isnt marketed as a boat cup holder!

Not for smaller handlebars. Theyll fit but they dont hold on tight. I had to line the inside with a little superglue, but as far as drink holding, decent. They hold bottles fine, my only problem was the slide. Its only a real problem when transporting fountain drinks.
