I kept one outside permanently for 10years + and used it regularly. No problems. The only thing was the blue rubber bits falling off pretty quickly but didn’t make any real difference. I’d buy another. They’re not the most stable but for the price they’re good and hold a road bike with no problems.
Are the workstands that you can get from Lidl still regarded as decent? Seem to remember them being forum approved a few years ago...
