I mean it's a simple wheel chock and it's certainly functional but it STINKS so bad it cannot be used inside. It even stinks outside. I left it outside for three days then put it in my car to take it my storage unit and no my car reeks. I guess I'm off to a local store to buy some so I can make sure they don't STINK.

SMELLS too much like rubber. It reeks actually of rubber / strong chemical smell. Can’t use this in an enclosed trailer as it will permeate stench thru out other furnishings. Probably best for outdoor use only on trailers or Semi-truck /soaked it in baking soda & Vinegar and stench still there after 24hrs of soaking.

Even in my enclosed 4 car garage these things are off gassing a very very strong weird off putting chemical smell that won't go away. I'm worried about the contents of the material and possible harmful gas emitting from these blocks. I returned them, very troubling stench
