Decent, the height adjustment is a little rough, not clean machined threads

I see some others mention vibration issues but I haven't experienced any issues at all. I do have 1 30lb shot bag on top of it so I'm sure that helps but I only put it there because it was on my old one. For the price I couldn't be more happy. Super easy to adjust, I am 6' even and my 9 year old grandson is right at 5' we can both use it fine. It is light years ahead of my old dicks sporting goods Everlast platform! Honestly I feel like it has just as good of action as the 3 thick platforms at the Gym. I am going to purchase a second one to install in my warehouse. assembly instructions are not great but assembly is so simple they aren't really needed. Great job to the Title folks!
