Easy to use and inexpensive device. Must have for owner of the aircraft.

Best $30 spent ever! Works great!

Easy to use. Does a nice job cleaning the plugs.

Worked amazingly well - the plugs look like new

Actually I am quite impressed. I set my compressor regulator to 80psi (10 psi below max recommended), gave three short 1 - 2 second blasts with the media, then another 3 second clearing blast and the plugs came out looking very clean. I had low expectations for my carbond up and oily plugs but they came out shining with a matte aluminum color. Just be heads up that the cleaning media can get wedged between the electrode and the fingers but is very easy to get out. I thought this was going to be messy but it wasnt. 5 stars.

Works well. Cleans up the plugs just fine and even does a good job of breaking up the clinkers.

Works very well. My only comment is that the rubber gasket that you insert the plug through is pretty thick. This blocks the cleaner from cleaning up most of the threads.

Worked as I expected, was somewhat messy with some abrasive getting out as it was being used. Still it cleaned the plugs fine. Be sure to get all abrasive cleaned away before installation!

Handling by hands is great, i found a good used mounted on tool boxe.fast and easy to use.

The cleaner worked well cleaning the plugs but the rubber gasket used to seal the plug into the cleaner had a very small hole. trying to push an aircraft spark plug into it would dislodge the rubber before the plug could enter. I had to remove the rubber gasket, stretch it over the plug then try to hold it over the hole to clean the plug. I need to find a punch to enlarge the hole to the proper size for these plugs. Other than that, it works fine blasting the plugs clean!
