Maxspeedingrods coilovers ?

Was browsing around for our Toyota Corolla coilover options: BC, Megan, KW...(which seem to be more various than struts/shocks) and found these:
Maxspeedingrods Adjustable Coilover Kit.
I found these on there website was wondering if anyone has these on there car ? and how the ride quality is ? This is my first time hearing about them, and they look pretty.
