AUTOOL Digital Compression Tester Automotive Compression Gauge 0-426PSI 0~29bar for Petrol Engine Cylinder Compression Test Tool Kit with Adapters & Hoses, 6 Data Saving, Backlit Screen

Great

So overall this unit is accurate… very accurate!!! Tested it against four other compression testers. HOWEVER! The title for the listing is slightly deceptive. You could possibly even call this my fault for not looking at the photos more thoroughly… but, this unit does not double as a leak down tester. The title contains the words “cylinder leak down” which is a bit misleading as there is nowhere to attach shop air to this unit for it to be able to perform leak down tests. I thought it might be too good to be true for the price… even still, considering what he good compression tester cost and for as accurate as this is, I still think it’s a great value…. I would give the products five stars, but I have to give it four for the inconvenience…. If I ever see that the title is changed, I will then change my reading to 5 stars.

Nifty take on an age old diagnostic technique. The ability to read and store compression data eliminates the need for a pencil and paper!

Wayyy better than the gauge type!

This is working with no issues recommend it

Didnt work out of box

Easy to use

So of course we have to have it! (Wait no, we NEED to have it!)Look I'm not going to BS you, if you're looking at it, it is what it says! No more, no less! There's nothing else like this as it hasn't changed in the last 80 years... Until now of course!If you want it, get it! It feels good and has plenty of accessories and a nice case. We spend a whole lot more for a whole lot less! (Could you imagine if this was on the tool truck!)In my tears, It reads correct, it's simple to use and easy to see.... No need to write numbers down!Autool has been around for a bit and are making moves! They are creating ideas and innovating diagnostics! If anything else that's what you will be helping to support and have a conversation piece! If you do mobile diagnostics then it makes you look "with the times" as well!
