Deeper Desk Cup Holder, OOKUU Anti-Spill Cup Holder for Desk or Table, Sturdy and Durable, Easy to Install, Enough to Hold Coffee Cups, Water Bottles, Gaming PC Office Accessories, Black

These work perfectly for 40oz tumblers. Smaller styles can still go in it too, and while they don't necessarily fill the whole space, I feel secure they won't fall out due to the deep style. The clamp mechanism has never failed or even loosened. The cup portion can be adjusted to have the handle slot where you want it, and because it pushes down onto the clamp portion it is not loose. I've actually purchased another 2 of these exact models to use on other tables around my house.

This cup holder works great. It is made with sturdy material. The clamp is able to hold my heavy cup well without loosening. I really like its simplistic but elegant design, especially being able to set it to whatever direction I want that is comfortable to me. Overall a great product.

Very sturdy and easily attaches. I appreciate knowing that my drinks are safe from my curious cats.

I don't like to use too much unnecessary space on my desk so i wanted something sturdy and easy to install and these just fit perfect ,its storage capacity fits all my drink needs and the design is minimalistic, i recommend and would buy again.

I ordered two of these at a time to use both at once because I usually have multiple drinks at my set up when I am gaming. These are perfect to ensure that I don't knock anything over when gaming. They attach to my desk easy and very well, the connection is tight, and the storage capacity is perfect. This versatile device is so helpful and very sturdy

Perfect size

I have a standup desk and it has a wide base on the top. I needed a cupholder, since I don’t have a lot of room on my desk. This worked out perfectly.

Functions as expected, using taller mugs and glasses is helpful. Fairly sturdy
