at how well this works.  Yes you can pinch your fingers but you have to be a klutz to do it.  Handles my 120lb shepherds with ease and they like it and it seems like it will last for a long time, very sturdy.  Not too heavy for the strength it has but at 18lbs or so might be a bit much for elderly or smaller folk.  Works well with SUV, don't know about smaller cars cause it is not small.  I and my dogs are both very happy with it and the price was MUCH cheaper on Amazon then at the pet stores!
