I'll start by talking about my car. I have a BMW 7 Series sedan that weighs in at around 4,500 pounds. I mention that to give an idea of how these handle that kind of weight going against them when I park. Anywho, I was originally hesitant about buying these having read reviews about them coming undone from the floor, and also getting crushed and breaking. I decided to take the leap and check them out and get some. I'll first mention, I have a pretty smooth garage floor. So if you have more of a rough concrete garage floor where walking barefoot isn't too pleasant, these things probably aren't for you because I don't image they'd stick too well. Anywho, when they came in, I gave the garage floor where I'd be putting them a good scrub. First with some of that amazing blue dish soap that comes in the spray bottle. To avoid brand names, I'll call it Crawn Powa Slawsh. After that, I used some rubbing alcohol on the concrete, gave it a good wipe, and let it dry. I pulled the adhesive off, and put them where I needed them. I pressed them down against the ground for a good 30 seconds, and let them sit for a while. I didn't want to drive against them right away for some reason. I've been using them almost daily with no issue so far. They always manage to stop my car just fine. You may have a different experience if you hit them too quickly or don't prep the floor so they stick well. But in my case, they've been excellent so far and I couldn't be happier.

I kept bumping the bikes stored in front of my car. I cleaned the concrete slab thoroughly before attaching these using the double sided tape attached to each bumper. The size was plenty wide enough so I couldn’t miss the bumper and after a month the tar has he’d well. Some people complain they are too “ low” but as long as you drive slowly into your garage, I don’t see an issue. I definitely know when I’ve reached the correct stopping point.

3 months on and these are working great and perform just as I hope they would. My car weighs just under 3 tons so I was concerned they may collapse under the weight but they are holding up just fine. Each day I pull in, roll up slightly on them, my car rolls back and I park and they have not moved. This allows me to leave just inches in front of my car, so I can get through behind the car with the garage door closed. I followed the directions and thoroughly clean the concrete before I placed them and I believe that has been the key to them not budging.

as described

Nice and wide, you don't have to be exact every time you park. I like the 4 reflectors that come with them they make parking at night easier.

Excellent quality. Very heavy plastic. Attached easily to garage floor. Does exactly what they are intended to do...stop the car before you hit the back wall of the garage.

Terrific box. Haven’t opened it yet.

Works great didn’t need to even secure them
