I own a number of these stands from Thomann, with slightly different branding depending on when bought.
Without a doubt these are the best value middle weight stands on the market.
Money/load capacity ratio is fantastic, and many more expensive stands hold significantly less load.
They are quite heavy, but this is good as it provides a very solid base, especially when lifting truss near the height limits of the lift.
As with all lifts, care and experience is required when carrying to avoid trapped fingers. Warning, they bite! I think they do carry bags for them, which would prevent that.
Only issues to date are that the rings on the sprung pins get caught and bent on things (easily replaced, they're keyring rings) and the plastic handles on the thumbscrews can get snapped.
Unlike most other stands I've owned, the plastic/rubber feet/bungs on the ends of tubes are all still in place!
Highly recommended
