Predrilled holes seem too small and wood is brittle, splinters the wood and finish as the screws enter the hole. Guide holes for Cam Lock Pins are inconsistent. 6 went in easily as holes seemed suited to job, then 3 were impossible, splintering the wood. Not sure if I will continue to wrestle with it. I feel Wayfair ripped me off. Can't leave it half assembled in the room while I wait for replacement panels. Much too expensive for the quality of the assembly preparation and the method.
