Review on 🏋️ GRASEP Home Gym Wooden Gymnastic Rings: Ultimate Body-Weight Resistance Training Kit with Door Anchors and Extension Strap by Antoine Scisson

This is one of the worst documented products on Revain. The product does not come with instructions, so you can set it up and use it safely. There is no website with videos or other how-to guides. There is a subtle invitation to contact David Zhou on LinkedIn to extend the warranty, but you cannot message him unless you are a LinkedIn Premium member! The product may be of good quality but for those of us who are unfamiliar with the nature of the product, it is useless to the consumer. The only help from other Revain reviews.
