After we had already cleared out the basement all day, I had to build these two shelves. Somewhat confused by some reviews I went to work, first briefly thought about the system and then began to put the different parts together. The whole was really from basic and simple. Well, a rubber mallet would be good to the Headers then finally to knock into each other. I needed for the first rack for 30 minutes, the second shelf was then in 20 minutes. While the floors look a bit windy, but for a basement shelf you keep enough of. The delivery was as usual very quickly and well packed. I had neither outside nor inside any transport damage. I have given it until today and with the weight came the stability and security. I am very glad that I bought this shelf, because the value for money is more than optimally and with the construction proceeded easily. I can only recommend it to everyone.
