The smell is so strong!!!!! Do not open in home or even your garage if you can help it!
I am using them as curb ramps for my low car and they work great for that. A lot cheaper than other rubber ramps on the market specifically for that purpose.
Great product for a garage or driveway. They are very sturdy and will retain several cords. They came quickly and were just as described. I would recommend using them.
This is just what I needed to run the 30-amp power cord and 1/2\" water hose over to my RV across the driveway. Both fit easily into the two troughs. Very well built.
