This product provides all the utility of the name brand version for a small fraction of the cost.I've read a few concerns in the reviews, but suggest you look beyond them:> Not safe concern with the over-the-door loop. Per images, the strap is supposed to be through the hole in the block -- it appears to be a manufacturing issue - not something inherently wrong with the product> Hand grip softness. Yes, the grips hard solid -- and I believe that's good! If that's an issue, simply wrapping it would solve the problem or wearing training gloves> Limited instruction - that's true! But look elsewhere for posters that cost very little -- you have saved a ton buying this version, you have afford a few dollars for a detailed poster. Also, there are many videos on-line to show proper technique.> No mounting hardware - that's true too. I spent less than five dollars for an eye bolt to mount to a 2x4 placed across joists in my unfinished basement.On the positive - everything else. The hardware (connectors and carabiners) are solid. Adjustments are easy to make - the straps stay put. The straps are high quality. The rings are well sized and sturdy. The foot loop is well made and easily fits my foot w/shoe. I have no concerns about its durability.Great product!
