Works great, all the tools for some basic to intermediate testing. The spark plug tester is easy to use and well insulated, the recessed plug adapter makes getting the checker hooked up to the plug a breeze. The only thing that I ended up doing was spray a little silicone spray on the rubber parts that slip into the various adapters. it makes putting them on and taking them off the spark plugs easier. the MAF tester and NOID lights work well and fit a variety of different harness types.
