### ⭐⭐⭐⭐⭐ the slot for the cell phone is not deep enough
*by O***I on October 15, 2025*

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.

### ⭐ Terrible
*by C***E on May 19, 2026*

Terrible product. They did not stay in place nor did they fit correctly

### ⭐⭐⭐⭐⭐ 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.
