It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

A Wonderful Update To A Great Old Reference Book!
Format: Hardcover
It's the Merck Manual! If you know medicine but are aware you don't know EVERYTHING about EVERYTHING! (Few if any do!) This is a wonderful reference. If you have no medical knowledge and think this will make you know what doctors know. Don't waste your money. You have to have a basic understanding for this to be helpful. This is a wonderful update to an old favorite.
