I've owned the Park Tool PCS-10 for four years or so. I think it's great, but it's not everyone's cup of tea. I noticed today that Park Tool redesigned it and it's now the PCS-10.2. The original was well made with welded gussets and a quick release at the base for folding. Very stable and the way it worked it was impossible to fold up while in use.

To me there's an obvious quality change for the worse. The new version uses crimped steel tubes, with mechanically fastened braces. Versus the old fabricated and welded base.
Two Amazon reviewers had the new version fold up while their bikes were on the stand. One reviewer had the stand collapse twice with their ebike on it.
There are other changes to the stand. The PCS-9 has been changed as well. I own a lot of Park Tool products, big fan. I don't like this change.
