This is built like a tank, really well made, lightweight, and perfectly designed for mounting pedals securely, whilst having excellent access for cabling. There was enough (super tough) velcro supplied to cover the full length of each rail, with some spare.
Suggest you stick the fluffy, softer side to the board as it doesn't pick up bits you can't remove.
Once attached, pedals stay perfectly in place and don't move about when using them. This is helped by the large, flat tops of the rails.
Cables can be routed anywhere you could want and zip tied in place easily.
Can't think of any improvement to this product, except to supply it with more zip ties.
The completely 'open plan' design (not having integrated cable / power as part of the board as some manufacturers make) was a bonus for me as it's to total blank canvas you are free to lay out and wire to your exact preferences, whatever your needs.
