Quality product and material. If adding side grip adapters or the high bar adapter to an initial purchase, it would have been helpful to know that you need to add the adapters and longer countersunk screws before mounting the wooden board to the module, AND that you can NOT use BOTH. There are two positions (high & low) on each side of the high bar adapter for side grips - while you could add two pair of side grips, it is only practical for one pair if using the larger grips like the Euroholds wooden grips. Overall, I'm very pleased, even though I have a pair of extra grips and side adapters that I can't use now because of the high bar adapter.
