I ordered one of these just after Christmas. When I opened the box I found the tach was off-center and upside down with parts missing from the box! I quickly e-mailed DK and they said to send it back for a full refund or exchange..well I finally got around to sending it back on Jan. 25 and it showed up at Dennis Kirks returns department on the morning of Jan. 30. Imagine my surprise when I got home from work on Friday (Jan. 31) to find a box on my doorstep!! I quickly tore open the box and found a perfectly centered and shiny new replacement. I can hardly wait until the weather turns nice so I can install this and get riding. (We've got 3 feet of snow up here.) The tach is smaller than the pictures would lead you to believe but it's plenty big enough to read and not look like an aftermarket item on the bike. Kudos to DK and all the gang in the returns department for their excellent service and willingness to stand behind the products that thy sell.
Installed on a 2009 Yamaha XVS950. Looks perfect and functions flawlessly. Needle is rock solid when running, no bouncing at all. VERY easy to install. Backlighting is bright and makes it easy to read at a glance. If your ride doesn't have a factory tach, I highly reccomend this one.
