In order for the price 1

You just can not expect the best quality at the price. If you want to lay a lot of square meters, certainly the wrong choice.
For us it was only 30 square meters, but the quality on the whole was fine.

Wedges:
Do their duty. Certainly not the most stable material, but do not slip and keep the distance. Those who want to can at the point of course with the waste he has lying around appeals. Do it often as well.

Crowbar:
Be careful with that thing. This can damage his fiberglass / plastic / Parquet very quickly. The small felt-sticker will not help there, too. The best a thin pad (laminate waste one has lying around?) Use it. Otherwise you quickly dents in beautiful new floor.

Tapping block:
Time rubber mallet, hammer normal times. Either way, the block looks 25sqm of not very fresh. But I think that each block of wood after editing shows such signs of fatigue. Maybe I cut it too tightly? Does, however, also slightly dented and chipped his service.

All in all, I would buy the set again for the price. Am happy with it.
