THIS ONE WORKS OUT OF THE BOX. I TRUST THIS ONE.
THIS WAS THE ONLT TOOL THAT WORKED OUT OF THE BOX, I HAVE TRUED OTHERS FROM AMAZON. THIS IS THE TOOL YOU WANT TO TRUST FOR EASE OF USE, SIMPLE, AND WORKED VERY WELL. WORTH THE MONEY, MAYBE AN ADAPTER OR TWO WOULD BE NICE. VERY HAPPY! Works well: VERY SIMPLE TO USE Why did you pick this product vs others?: OTHERS DID NOT WORK AS WELL

Leak or no leak?
Excellent product and worked as intended. In 15 minutes or less I was able to test if my new custom loop had any weak spots or not. Air leaks easier than liquid, so you can feel confident when testing is over that your good to go. As always, after a few heat cycles make sure to double check all of your fittings.

Better than others
Bought the Thermaltake version (pos) and it leak like crazy, bought this unit to replace it. All I can this is the one to buy. cost a little more, but worth it. Only thing I would change is the fitting sizes so you don't connect the wrong pieces together and think it doesn't work right.

Defect

Excellent build qualiyty
Build quality is excellent and I was surprised at how good it was. Does the job and lets you know if you have leaks in your loop.

Well made. Does the job well.
Works perfectly as advertised. Easily connected to my loop and added some pressure with the hand pump. Gauge was easily readable to check for drops in pressure. It's one of those tools that is incredibly niche, but when you need it, you need it and nothing else will do.

Worked fine until a leak a year after purchase.
Worked perfect first time, now using it about a year and a half later, has a leak at the hose end. Disappointing considering I sprung for the expensive EK leak tester, which I now regret. If you donโt need something quick or can get one just as fast, Iโd recommend bykski or barrow.

Good construction and easy to use
I got this pump to make sure I don't have any leaks before putting the coolant into my custom loop. This actually helped me find a gasket that was squeezed out of position. Very happy about having this tool.

Works
Works as intended, took 2-3 weeks to deliver, but works and is good metal material. The pump stick can get unscrewed constantly by small movements, so you have to tighten that before pumping constantly, small annoyance. Connects into an EK GPU water block and Corsair hydro X attachments.

Bloody good quality!
If you need to pressure test your water cooling before filling (which Iโd recommend) then you wonโt find better than this for the price. Absolutely solid piece of kit

Giunture morbide
Prodotto di buon materiale ma le giunture si svitano troppo facilmente e ogni tanto se non la tieni salda con le mani perde un po' di aria e ti fa impazzire...
