Sent my Nikon P900 to get checked out since it had been dropped. Wasnt sure if anything was damaged or a little off. I was afraid to ship the camera anywhere but there were no local choices near me. They checked everything on the camera. Tested everything, had several different techs look at it. Fortunately nothing was wrong. So for all that testing etc. they didnt charge me a dime except for the agreed upon shipping. I was totally prepared to spend on a diagnostic charge. Camera was returned promptly and cleaned. Was kept up to date on the whole process. Will use them again if needed. Highly recommend.
