Good value, but I’m left wanting.
Does the job. Quality feels adequate. Probably better suited for small engines rather than automotive. While I feel like it’s a good value, I knocked a star off for it not having an adaptor that is a long reach 14mm. So I could not use this on a 3.0 Vulcan engine.

Garbage
China junk. Save your money. And if you decide to buy it anyway, don’t do what I did and wait to try it till after the return period has expired. I spent my whole day today trying to make this thing work. The threads are wrong on the whip that threads into the spark plug holes, the air inlet npt fitting is is also not correct. Upon finally getting some air into the thing, an o ring blew right out on the other hose. I nearly chucked it deep into the woods, from one mechanic to another, don’t buy this one.

Piece of mind purchase
Ordered and received the product on the date stated. The crimped connector on the hoses are tight, first thing I checked. The quality was good. The tester work great. Good price.
