I use mine fairly often. I had an old model that was a slight PITA because you had to level it to be able to use it. I now have the newer model that has 3 accelerometers and does't require leveling. It's also very close to actual 1/4 mile runs. That's alot better than the old one. I've actually tested it at the drag strip and compared the results to the time slip. They were very close (within a few %).

The newer model also lets you download the data to the computer and print out results if you want . In short, I feel that I've made fairly good use of mine over the last several years. You really should get it out a play with it since you already have it.
