That's part of a problem I realized: You can't use skateboard or rollerskate parts, which means that especially regarding price, availability, and quality, you're totally dependent one this one single company (also regarding variety). Without competition from other companies each of the parameters is likely to be better for the company than for the skater. The stoppers, grind plate, steering system, etc are all non-standard as far as I can see, a buyer should be aware of that.
The company should at least make the skates compatible with wheel standards such as inline or even skateboard/rollerskate wheel systems.
