Question about Gardena Comfort 400 C

Have been using it for 2 years, still stable, nothing wobbles or crumbles (stands outside, rainproof).

The orange plastic nut on our unit broke (after about 3 years). Probably due to improper tightening. The replacement part could be reordered from Gardena, but it took weeks for it to arrive (perhaps because of the special circumstances in May).

It seems very stable to me. However, I have only been using it for one season.
