I am a professional columnist and consumer product analyst. There is a "body language" present between the lines when someone writes reviews and complaints.
There are big red flags when someone writes with the intention to pose a false statement or impersonation. It is obvious, with the ratio of complaints and "praises", with complaints greatly exceeding the latter; that review is an attempt to distract a reader from the complaints. Upon a courtesy test from the Seller, the product fails in many ways. 1) the product is not safe, but just clears those Federal guidelines that allow it to be marketed.
Imagine purposely walking on cement steps that are glazed with ice just for the benefit of exercise. 2) Rub you hand in the same pattern as the product would do on carpet or hardwood floors. The skin on your hand will heat up rapidly and cause serious injury. The board will do the same to your floors.
3) The product is manufactured from a plastic composite that will fail over time based on the wear and weigh-load distribution. Consumers fail when they allow hype, omission of details, and "slight-of-the-hand" to base a decision on a purchase. Do your homework and read all the reviews on sites such as this. Google is your friend when you need to see what others are saying.
Don't waste your time with the false and padded reviews on the Seller's site. If something doesn't feel or look right, walk away.
