Didn't work - UPDATE 11/11/2018
October 22, 2018
Tried it on a 21hp mower and it didn't work - tried on a 1999 jeep 4l 6cyc also did not work. Sent it back.
Customer service is outstanding - after sending the first one back, I was contacted by a CSR and they sent me a new unit immediately. The carrying case and attachments are all top quality.
I charged the unit for 24 hours and tried it on both the Jeep and Craftsman rider and it worked fine - no problem. Very happy to have such a small unit to carry in the car. I would certainly buy from this company again. A special thanks to the representative who contacted me.
