I recently had my Bandido ii umax checked out....I bought it used a few years ago...I talked to Rusty and to the lady...I was charged 50.00. When I got it back I could see they had did some work on the coil...It took around 10 days from the day I shipped it before I got it back...Tesoro was awsome...Also I have a Whites Quantum pro that wouldn't turn on....I took it to the service center near Lombard, il...He adjusted the battery pack terminal on the spot at no charge...He also sold me the chip to update Quantum ii for about 15.00 if I remember correctly....Service is great at both tesoro and whites...I also have a G2 I bought from Monte last fall....Hope there service is as good if I ever need it
