If you have a pedalboard and struggle to reach the pedals at the top, then you need one(or more) of these. They will help you to reach the switches without stepping onto the knobs of the pedals below it.
A competitor StageTrix also offers a similar product(which I own two), however The Harley Benton is as sturdy as the other one, but with one huge difference, the raised are is larger(as the corners are nearly 90 degrees up). This gives the this product more sturdiness. If you rotate sideways, you can put two slim pedals in one unit.
Both StageTrix and Harley Benton use the same amount of space on your pedalboard.
Cabling becomes much nicer as with the raised platform you can hide patch leads and power leads underneath the pedals.
If you have a double size pedal, like Boss VE20(or delays, etc) you can use two of these risers and the unit is supported perfectly.
The only point which would be great is for pedalboard that have 3 tiers, so a taller unit would be great ( I have an MXR pedal at the 3rd row, which still needs my old wood riser on top of this. With that said, I also have a Boss pedal on the top row which needs nothing but this riser(as the Boss is a taller unit).
Simple summary, if you are a guitarist and have more than 2 rows on your board, then your life will be much easier with one of this.
