Let's read it for what it is, it's a cheaper version for people who want to have the ability to do leak down test themselves. This isn't exactly marketed at pro mechanics and I doubt you'll see them in big name shops. Look for the average Joe that's going to use it every now and then it's perfectly fine for that. I don't know how much I would trust it's accuracy in anything too critical but dealing with little cheap small engines I'd say you're good enough with this set. Here comes in its case with some included adapters. It's priced very reasonably and if you've ever priced any high end testers you'll know you couldn't buy one of the spare adapters from those kits for the price of this entire kit. I'm going to say it's a solid four stars but not quite a five, The plastic parts of it and the gauges themselves feel very vulnerable to easily breaking and the case itself is a little bit off where things don't quite like the push into place and stay secure. I don't think their deal breakers if you just need a cheap kit to be able to have the ability to do a link down test.

This tester works great, helped me locate some valve leaks and saved me from a complete teardown. It could use a better assortment of adapters but I have a compression tester with a full assortment of adapters so for me this is perfect.Would recommend this leak-down tester.
