I actually expected to test a wobbly plastic shelf, but I was pleasantly surprised. It is after the quick setup (Easy understandable thing) actually a (relatively) robust Regal came of it. However, the stability also depends on the weight of the things that are stored there. According to instructions about 40kg load maximum possible. However, should not be placed completely above, but who does that. I have it now in the basement available for my shoes and winter clothes bags, and then soon summer garment bags. In the bedroom or some other room like it "visible" then not so good, but functionally it is really perfect for such as a laundry room or basement flat.
Conclusion: a stable "small" shelf is quick to set up and functional, very good.
Addendum: Only now the price has been set and I have to say, scarce 27, - is truly awesome, I thought it would be twice as much. For the rack / cabinet is a bargain.
