BETOOLL 8pcs Petrol Engine Cylinder Compression Tester Kit Automotive Tool Gauge

Looks great haven’t used yet but quality for the money is great!

This is a great tool. Works great

Does the trick for a DIY-er but probably not recommended for a serious hobbyist or shop. The hose itself must be twisted into the sparkplug holel. This twisting of the hose will likely damage it in relatively short order. The kit really should include a 6" - 8" extension tube to get into the spark plug well on cars with on-plug coil packs.

Worked great. Plenty of adaptors

Works as described. Great price

This is a very nice kit.I already have a 14 mm extension tube that runs down that you can put the tester on. I’ve never been comfortable with the testers that you put a rubber hose in with an O-ring because on a rare occasion it’s really hard to get those out and I’m speaking from a spark plug it down inside the head, for example, on a twin motor like it’s a great price. I think you’ll be happy with it.What about the rubber hoses have the solid straight tube and one angular tube that you put the meter directly on and you don’t have to worry about something coming loose. You just have somebody in the car tap the starter a few seconds and then you read the spark plug cylinder kit.

Great product. Worked great.

I have compression but it’s not very accurate. I checked it against my air compressor and it read 115 psi. The compressor was at 90 psi. The engine I checked had 130 psi new but I got reading from 100 to 160.
