Love the grinder, hate the abrasive rating system
I really like the 125v grinder, but the replacement roller description for abrasiveness is stupid, and that's why I knocked off three stars.  Holy tuna on a pogo stick, why not use an industrial abrasive rating?  Terms like  extra coarse, extreme coarse and Super coarse are meaningless, (quick - tell me which is most and least abrasive)  and more so since Amazon sells aftermarket rollers that use different naming and color schemes.  They also imply there are medium and smooth or polish, but it isn't mentioned on Amazon that I can find.  So I went to the Micro-Pedi web site:  emjoi dot com/Refills.  Some usefulness there, but why not make a comparison chart so one can just scan a table and make an informed decision rather than have to open up each item listing, read the description and build my own table, one for the factory stuff and again for the aftermarket?<br /><br />I know, it's my engineer's left-brain at work.  Sorry - If my rant can get the vendors to fix this it would be worth it.<br /><br />By the way, holding a new no-name aftermarket green 'extreme' roller @$2 each and a blue roller that sells for $10 each with  'MicroPedi' embossed on the end, they felt identical.  In use, the blue roller with the factory name went bald in about ten minutes: I mean there was no abrasive remaining for the majority of it's length.  I put about 20 minutes on the no-name green roller and it still has some abrasive.  Not a good sign for the name-brand stuff and a total rip-off considering their greedy pricing.
