Review on 🥤 RAM Mounts RAP-B-132B-201U Level Cup 16oz Drink Holder with Double Socket Arm & Medium Arm - Compatible with RAM B Size 1" Ball Components by Jose Mcdaniel

The cup holder contains a blue foam biscuit that won't fit in your 20oz mug and will wobble without it. This is because the cup holder is not deep enough. You think it's going to be deep for a smaller cup, but the smaller cup wobbles and now you need a blue foam cookie to fit in that smaller cup. The best design helps, the diameter of the cup holder corresponds to the norm. Standard cup diameter (3 1/2 inches) Meanwhile, just to help new customers, it would be great if you posted the measurements in the product description.
