I've actually never ridden a Vmax on my personal scooter but I've had the SMX, SMX v2, and LinX, and never had a problem with any of them so it's pretty safe to say the Vmax would perform to the same standards.
ive owned a pair for a few months. for like 50$ its legit how you can get a integrated starnut. the only problem i had was that i got them shortened by vertx and they still dident fit my baby scs, just a heads up
