I got used to ramps like these when I was working at an aerospace firm. We had them everywhere in the high bays because we had cables everywhere. Some of the cables were esoteric, delicate, RF cables. When rolling a hand truck over a $7K cable could destroy the cable, you take precautions!What we used were a size up from this, but this size is ideal for my home workshop. There's no sense having a taller trip hazard than you need, so this is perfect for my use. Given the modest price of this, I didn't expect to receive anything this nice. Nothing about it -- materials, design, or workmanship -- suggests that this is a "low rent" item. It is very high quality and it's heavy so it will stay in place. To the smell-sensitive among us, I didn't notice any offensive odors.You don't really appreciate these until you work around them a lot. Then you really miss them when they are not there.I actually plan to spend my own money on more of these (hopefully when the price drops or they are put on sale).I am happy to give this product a five star rating and to recommend it.
