The construction technique is basically simple, would not be material to the screws completely deficient. The technique is known from other quick construction: corner joints be secured with locking screws. In this cabinet the lock works only in a few cases, sometimes not attack the lock wg, accurate holes, usually bend the screws or even break off. This is particularly unpleasant when the screw breaks off directly on wood and then has to be drilled out.
I ultimately the cabinets additionally glued (but this large clamps are required), so that the construction took several days due to the drying time of the wood glue.
Conclusion: visually beautiful wardrobe, but whose construction wg. Remedial craftsmanship, appropriate tools, and above all strong nerves needed.
