I already have the curved version but decided to try this straight version because it is shorter and I use a double bass drum setup and two of these beside each other make up for a more appropriate span for my setup.
There is no slippage whatsoever, of course, unlike certain other brands' round bars. These bars are squarish/rectangular and the clamps attach to it and there is no way that they slip. It's physically impossible.
There is nothing absolutely that I don't like with this rack. I cannot find any faults or drawbacks.
Get it if you want something reliable, solid, strong, and light.
This is all about this drum rack. Highly recommended! As I said, unlike other round bar racks, this one won't disappoint!
