Does Anyone Know Where to Get Hizero Non Genuine Accessories?

Hello all,

had the hizero for a few years, its great, but buying new rollers every 6 months starts to add up,

for some reason i have to pay them $30-40 for a roller that would normally be about $6-8 on aliexpress but i cant ever find any aftermarket ones.

anyone seen these in their travels?

the unit is made in china, dont know how i cant find copies or genunie items out there.
