A very sturdy ramp, but first, the metal bar that holds the two pieces together keeps slipping out of place, so you have to make sure to put it back before every use; and second, you need to add anti-slip strips because the plastic is slippery.

good construction. my dog is 30 kilos. In the previous car that was low, he climbed easily. In the current one that is high, the incline is greater and he enjoys it a lot.
