JOYTUTUS Wheelchair Cup Holder, 2-in-1 Walker Cup Holder with 6.4'' Large Storage Box, Drink Holder for Bottle with Handle, Fit for Wheelchair, Walker, Rollator, Stroller, Camper, Golf cart (Large)

Best of both worlds for the size. Dads coffee cup is a little under 3 1/2" (90mm). The choice to purchase this cup holder was for the 4" (100mm) opening. The cup would not fit. There are 4ea silicon tabs that hold a smaller cup securely in the cupholder. In order to get the 3.5" cup in the 4" hole we needed to remove 3 of the silicon tabs. This works great as he has 3 cups this size and that is all he uses. The holder is mounted on his walker.The problem with mounting on the walker, at least on the outside is you lose a lot of door clearance. We wound up removing the cell phone holder (storage container) and remounted inside the walker. He will not be able to move the seat all the way up to access the cargo area and if he needs to sit down he will have to remove the cup holder.There is also a silicon mat in the bottom of the cupholder and the storage container. They are not mounted with any adhesive so I am sure it is a matter of of time before we lose one of them... again.There is also a small silicon piece that the bar clamp needs to grip the walker. You will be chasing it around until you get it mounted.This is not self leveling. Once you have your mounting spot you need to unclip the cup, locate the allen key (tool provided) and turn it around to as close to level as you can find.Was this worth the effort? Most definitely. A little pricey compared to others however for the buid an quality, it is worth the price.

Worked great on my Knee Rover scooter. It held most of my cups easily and my cellphone. Easy to clean and remove. Good size for my needs.

Love it! It’s working great for my walker and my big cup. Seems to be a great fit for me. Doesn’t seem to spill the cup as other holders have done. Very happy with this.

Fits easily on Mom's wheelchair and holds her phone, drink, Kleenex, paper and pen easily. Unfortunately, it is not as sturdy as we would like, even when not fully loaded, and we have had two break when they are bumped by someone walking by or another wheelchair. If it was made with a stronger material (wire mesh perhaps?) it would be amazing because it seems to be the only one out there that fits easily and holds "all the things"

It's pretty good, the rubber pad that is supposed to line the bottom of the phone holder part was missing, the one in the cup holder was inclosed.Not worth returning over, but would be nice to have.That's why I deducted 1 star.For the price, it's not as heavy duty as I expected. But it at least holds my mug and phone while I'm using my knee scooter.

Must have for wheelchair users. Easy to attach. Convenient for drink holder, phone, miscellaneous. Good quality. Recommend take off to sit at tables, but easy on and off.

I was pleased with this product. One tip make sure you know what direction you want the clamp to fit before you hook it together because it is a tight fit and hard to move once you’ve done it. But I was very pleased with the quality and use of the product.

Works great
