Has anyone here used the Ride Safer safety vest? Can be found here. safetrafficsystem.com
Looks like it may be a good alternative to a booster seat. I like how it's still a 5 point harness. Plus probably give my son and wife more legroom. Just wondering if anyone else has experience with it.

 

I have it, it's just a little bit of a hassle to put on the kids that's all.

 

Used it, but didn't like the hassle
