ET105V 16 PCS Universal Radiator Pressure Tester, Vacuum Type Cooling System Kit for Universal Vehicles,Made in Taiwan

I say intuitive because it has to be, there are no instructions. Since it is a automotive cooling system pressure tester, I expected to have to use an adapter to connect where the coolant is added to the system. I picked through the numerous adapters provided, and found one that looked like a good fit. Right the first time! It screwed right on my expansion tank. Then I looked at the pump assembly and saw it was a snap fitting, and the adapter had the matching male fitting on it, so I snapped the pump onto the adapter and started pumping away. It took awhile to get it to 1 bar, and it seems to be holding - I'm writing this review to give it a chance to bleed down and hoping it doesn't.
There are a lot of parts in the kit, all arranged nicely in a latching plastic case. I have no idea what most of the parts that are not adapters for various types and models of vehicles are, and probably will never have a reason to find out. One item is a temperature probe, somewhat similar to the one you use to see if your roast is done in the oven. Looks nice, but I don't expect to need or use it.
All in all, having owned it for about 10 minutes now, I am very satisfied with this purchase - the cheapest unit I could find on a decent car parts website was about $200 - too much for my purposes, and I could not find one to rent locally.;

Worked as intended;

Had to grind another Honda adapter to make it work.;

Item works perfectly, easy to handle and simple to use.;

It was good material and easy to used good delivery times;
