ihad it for a year now and its been out 3 times to be repaired its good when it works but that's hit or miss , I contacted snap on directly and got nothing but a run around , my local dealer got it resolved but now I'm so leery of it and I don't trust it , and ide never buy snap on dio again , especially how the corporate acts like they just don't care , 11grand and I couldn't get them to do any customer service only reason I give it a 1 is cause rating must by higher than zero
