I bought an Acutrac III Plus 11/2011 and only used it 3 times and it went TU. I called Perfect-10 to find out where to get fixed and they told me that they have NO repair places to have it fixed. Also they said if i bought it from a third party there is no waranty. Just FYI beware of where you purchase. Personaly I do not recommend it. For 250.00 I would expect some kind of customer service from the mfg. Save your money.
