Review: the slot for the cell phone is not deep enough - The material and price Look good; The cell phone slot is not deep enough, It's a little tight for Toyota Highlander but good for the Ford Explorer.
Review: Waste of money - I have a 2025 Jeep Wrangler and these do not fit. Currently, they are not in use as I get so aggravated. I pulled them out and threw them in the back trunk. The two I put in my jeep grand Cherokee are the same and they work OK. So depending on your vehicle, keep this in mind. Sometimes advertising will sell you anything.

### ⭐⭐⭐⭐⭐ Kept me from losing my credit cards
*by O***R on June 15, 2025*

I bought these to fit inside of my Mercedes Benz MLB and they fit great. The installation was easy and the quality is great. They are strong and very functional. I can store my phone or a small wallet there. It keeps things from falling down under the seat and also keeps things that I need handy when I’m driving. Good value for the money and I would buy these again.
