Review on Premium Quality Rubber Wheel Stopper – Zento Deals 2-Piece Parking Tire 🚧 Guide Blocks with High Visibility Reflective Strips in Garage Professional Grade Durable Material by Demetrius Young

The quality of these parking stops wasn't what I expected. The reflective tape used in their manufacture had completely fallen off by the time of delivery. The adhesive backing of the reflective strips seems to be good. it just doesn't stick to the molding. I thought these things were molded with a softer rubber compound so they would stick to my garage floor without having to bolt them on. They are molded from what appears to be recycled plastic chunks and granules, perhaps with some added rubber. They resemble a hard plastic part rather than a softer rubber part. They don't lie flat on the floor because they came out deformed and misshapen during the molding process. I had to cut a lot of ridges along the parting line from the bottom edges. The screw holes are filled with plastic and need to be drilled if I want to screw them to the floor. The ribbing on the back of the pieces is totally different from what was shown in the photo on the product page. Other than that, these things are great. I wish I had bought more expensive grommets from another supplier (which are actually molded from a softer rubber compound).
