Review on UMISKY Expander Multifunctional Extender Adjustable by Jon Conner

Does what it promises. For us, we had to use the included foam pads to make it fit better in the car's cup holder so that when you add the second drink it's balanced and doesn't fall to one side. The part where you adjust to fit a larger bottle, like the hydroflask, becomes wobbly when you're trying to drink in a smaller cup holder and the hydroflask is pushed to one side. This will work and if you put all the foam pads on top of the device it will likely make it more durable. We only did three rounds in total (see photo).
