Unpacked cardboard, the first impression is the fragility (for printing have to mount Meccano) but once finished, all solidified and established is very stable.
Once the general frame mounted, it goes very fast, provided you have the tools that go well: Screwdriver (avoiding screwing without force adjustment) and keys 7 and 10.
2nd obstacle mounting the drawer, do it two, all alone it's horrible. For those who go backwards to the slides there in a small plastic tab on the inside of the slide (I put a lot of time trying to uncouple the two parts)
Regarding the plans of wooden work, I fixed only the top one and I put the screws with bolts for better stability rather than the pokey small screw provided. Other returning forcibly into their homes, I did not find it useful to tighten, perhaps later.
So why only 4 stars, simply because there really for the necessary hardware (not for error) and hardware is relatively low end, personally, I think if I have to remove the 3/4 break of screws to the presence of a few screws "cracked".
Otherwise it is very good, I even added light for late bricolo ;-p evenings Here I hope it will help to choose
