Customer Reviews for VEVOR Portable Speed Bump, 9.8 Ft Length Speed Hump, 8.66" W x 1.97" H Rubber Reflective Speed Bumps for Asphalt Concrete Gravel Driveway Roads Parking Lot Used On Car, Truck, Bus, Trailer, Streets

I have a really long driveway and was sick of people speeding down it. I bought two and they work perfectly. Has stopped speeding by 100%. If you hit these fast you will LAUNCH!!!!They don't seem to move around too much, although I may anchor them down in the ground just so I dont have to worry about it. 10/10 would recommend and may buy one more!
