Rated 4.5 out of 5 by 4 reviewers.
Rated 4 out of 5 by good compression tester works well November 26, 2016
Rated 5 out of 5 by Very accurate Great quick connect to air hose features if you have a universal coupler. And extras. September 23, 2016
Rated 4 out of 5 by Product has great features Works well... Has multiple fitting for most engines/motors. A great tool for the do-it-yourselfer. January 19, 2015
Rated 5 out of 5 by Compression Tester is adjustable for different jobs I needed a compression tester to check my John Deere tractor motor and this tester had a variety of fittings to do just that. It came with 3 or 4 different spark plug adapters and a long shaft for getting those hard to reach places. The price point for this tool was very acceptable and will go in my tool box to be used in the future for small and large engine repair. Oh, BTW, mine did not come with a storage pouch unless they are talking about the molded clear plastic display case that I had to cut open to get the tester and accessories out. September 17, 2014
