We own one and it works as it should, I don't believe the cost was worth the product but it does come in handy when we need it, that being said I don't thing we will be buy another one
Have a full set and got them second hand 4+ years again and besides having some dog hair in the Velcro they look and work exactly the same as when I bought them.
We have 6 total platforms from rogue and I will say the Olympic platforms leave so much more room for strongman events that I will probably replace all our deadlift platforms with oly platforms
