August 6, 2023Good test kit. This kit came with many different adapters and some spare o-rings. I used it to identify a dead cylinder. This is a nice kit with hard case.

July 1, 2023Nicely outfitted kit! I purchased this product based on price, features and the included case. I was skeptical of other less expensive brands advertised on Amazon. I found this same item for sale at O’Reilly Auto Parts, but it was more expensive.

March 29, 2021Quality tools! I bought this to replace a $20.00 compression tester kit I bought on Amazon about a year ago. I had assumed that a tool that is so simple should be pretty accurate no matter who makes it but that wasn't true at all. I compared the compression readings from this gauge to 2 other name brand units and they were within 2-3 psi.
