Review on 🔄 Enhanced 2 in 1 Multifunctional Cup Holder: Expander Adapter with 360° Rotating Base for 17oz - 20oz Bottles and 5.9" Coffee Cups (2 in 1 Cup Holder) by Nathan Issa

Nicely made but the plastic is flimsy and one side of each cup holder is spring loaded which is good if the spring is a bit stronger especially if your mug is much larger than a coffee cup then it will fly Your cup around the corner because either the height of the side walls holding the cup is not high enough because your cup will be too heavy for that, or the tension of the spring holding the cup is too high. too weak to hold your nice big coffee mug. So there is definitely room to grow.
