Encouraged by the reviews I ordered the same 2 boltless shelving. Now a shelf is stable and secure. However, as casual loose as described, it was not with me. After various curses, sweat drops and scrapes on my hands the first shelf stand for two hours. For the second shelf I expect significantly less time because I know how it goes. To build, you need a hammer and good light. My Kellerfunzel was definitely not bright enough, so I have the catches more palpated as seen.
