I had a similar one. It works well, doesn't scratch the rim and is solid enough for me to transport a bike in the bed of my pick-up truck, almost w/o any help from the tie-downs. If it was bolted down to the bed, I'd probably try it, for science...
In the garage, I've been on and off the bike many times, while adjusting the suspension and explaining how to lean over on a race bike to a friend, no chance of the bike tipping over.
The only reason I said I "had" one, is that I have the opposite problem. I wanted a chock that easily folds relatively flat so it takes less space when I am not using it, and the version I had didn't. I ended up with one similar to this:https://www.ebay.co.uk/itm/123480373096?
Because, as you can see in the pictures, it's easy to disassemble and store when not in use. It also happens to work better in my truck, but I don't think it's any more stable.
