I have already built several of these shelves. The high-quality wine I would not entrust this shelf. For this purpose you should obtain a more stable shelf prefer.
The wood is indeed sufficient size, even if you already feel that the construction will not ultimately be very stable. At two shelves, the pads are broken because large knots unfavorable, almost over the entire cross-section documents. In another shelf gluing was not performed properly, so I had nachleimen before I was able to build the shelf.
The assembly is quite fast, the holes are pre-drilled and for the correct distance you have every time you connect remeasure again, sooner were once distance woods here that have been placed underneath in order not to be judged, at the last shelves these were no longer but with thereby.
If there are several shelves side by side, you will notice how they are ultimately wrong, this should be kept in mind if you want to install more shelves in the basement.
Ultimately, you pay a small price for a low quality. I forgive 2 star, although you get a lot of quick and easy Strauraum and my oldest wine rack is, after all, been 5 years, but be given a minimum quality of the material has to be here and yet to be desired.
