Snack Bowl for Stanley 40 oz Tumbler with Handle, Compatible with Stanley Cup 40 oz with Handle, Silicone Reusable Snack Ring with Lid for Stanley Cup Accessories (Cream)

First point, I don't have a Stanley cup. But I DO have a 40 oz YETI tumbler which is the same size but no handle. The snack bowl fits snugly at the top and does not feel like it will slip down or fall off. I kind of love the bright pink and believe that Barbie would approve. Silicone feels sturdy and substantial and will hopefully last for seasons to come.This bowl is pretty large. It would be unwieldy to use in a car cupholder but I'm considering that it might be my go-to for the summer when picnics, finger foods, and charcuterie are all I want. I do have concerns about top-heaviness so I would be hesitant to have a full bowl and an empty cup. The lid makes a decent seal but is definitely not water or airtight. I have not tested but suspect that chips or crackers would go stale after a bit especially if something juicy (dips, fruits, etc.) were in the opposite side.

I like the snack tray but the lid doesn't secure on top very well. I already have a stanley snack track WITHOUT the lid so I wanted the lid part to work; its the whole reason I ordered this.

This snack bowl is super convenient to have some snacks when stuck in traffic. This has a cover so can use it over the tumbler or without. This bowl is well made, and well designed. soft plastic. Good quality, durable and sturdy. Easy to clean. Fits snug on top of Stanley tumbler so it works for what’s made for. Recommend it and happy with this product

Great addition to game night. It fits well, even on my knock-off stanley cup. It washes well, holds plenty of snacks, and allows easy use of the straw. The straw topper is also adorable and works well - it's my new favorite. My only complaint is that the color is yellowish and it makes it look old and dingy right out of the box.
