We've all done it: dropped something into the seat gap inside of a vehicle. One product promises to help keep things from disappearing into that gap.

We put Drop Stop to the test on Does It Work Wednesday.

Drop Stop says you'll never have to search under your seat again. This product promises to help you mind the gap and keep your stuff from falling in.

The device is made of high grade neoprene and it's easily installed, just slip it over your seat belt.

While driving, we dropped a small earring, thin lip liner, a penny and a stick of gun into the gap. None of them made it past the Drop Stop, not even on a bumpy road.

We tried Drop Stop in different vehicles and, thanks to its stretchiness, it still fits like a glove.

This product does everything it promised, so it gets a thumbs up.
