how long does a replacement cartridge last?

It will depend on how rough the heels are or how big a callus is. May require 2 (or more) until you get heels/callus smoothe. I can tell you that I love the Micro-Pedi vs. the PediEgg & will not mind purchasing replacement cartridge when I need to. Actually, I purchased 2 extra cartridges when I purchased the Micro-Pedi; haven't had to use extras yet.

I bought an emjoy miicro pedi, but the bottom where I put the batteries broke, where can I find a replacement, it's only a few months old

I would call the place that makes the micro pedi they may direct to where you can get a back. Hope this helps otherwise you may have to tape them in.

Which color roller is more coarse than the blue one?

According to Emjoi, the dark blue one is Extra Coarse. I don't know of any that are more coarse. They work very well.

I am a professional manicurist and I just received one as a gift!Since then I have bought 3 more and 10 refills! I Love this product, but my question is how to clean the refills for further use/ or back them up per client! Sanitation is very important! Thanks!
