Review on A ABIGAIL Universal Floor Jack Rubber Pad Adapter: Pinch Weld Side Rail Protector Puck/Pad by Duane Ramos

Appears to be made of good quality materials and the grooves are quite deep which I liked. But it was too big for my 1.5 ton flat Harbor Freight racing jack. Thankfully, it's eligible for a free return. I bought something that fit my particular jack size well and was made out of aluminum. The one I bought is made by Potauto and has straight grooves on the bottom to keep it from slipping off my jack pad.
