Chances are .....

.... You get delivered a defective board. Price performance is OK but I'm sure it gotten so tired of having to tremble every time anew whether the Board ordered after unpacking kinks in the surface has or not. If we did not want to have uniform boards necessarily in our company, we would have nothing to buy here. The Dinger also looks at anyone before they are packed?

The problem we have had both 120x90cm as well as in the big sizes 300x120cm. The latter was even delivered 2 times faulty. The coronation: While we have also for the 2nd Board Replacement get but the old board was not picked up. That could we then dispose of it yourself ^^

Sorry for this harsh statement but "Master of chunks boards" would make better.
