Mine quite working after 8 months.  I found out from Ivation that there is a 12 month warranty where they will repair or replace the machine, HOWEVER the cost of shipping the defective unit to Ivation is on you.  Given the size and weight of the unit, I am guessing the shipping will be at least $45, whic is almost half of what I paid for the unit.

If you are interested in a warranty repair, email a copy of your receipt to info@myivation.com with a note that you are requesting exchange under warranty.

I'm still debating whether I will invest another $45 in getting a replacement or try another brand.
