I purchased this to replace a similar board (without the wave) that had cracked at the screws and was tearing clothing.  The slide is designed for a 4 ft high platform.  It was wonderfully used by my grandchildren on a recent visit.

 It would have been helpful if a slight angle had been placed in the final 2 inches where the screws are placed.  The plastic has to be slightly forced into place with the screws placing extra stress on the plastic which could lead to fatigue and breaks in the future..   

Pros: easy to install.  durable
Cons: Attachment site had to bend slightly when screws placed.  May increase risk of fatigue and breakage hopefully far in the future.
