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.

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.

Slightly overpriced, but peace of mind was worth it
Easy to use, just remember, if you have a slight leak over considerable time, you're most likely going to be fine for liquid. Air seeps a lot easier than liquid does. Make SURE you don't crank it all the way up, my distro block recommended no more than .3m of pressure to leak test. This helped me save not having to drain and rebuild my system over and over. I had a fast leak I couldn't figure out, and it was coming from a 90 degree rotary fitting that I had downward force on, so it was creating a gap in the rotary seal. It would not hold any pressure for more than a few seconds, and if I tinkered around with the fitting, it wouldn't build any at all. This might've passed a normal fill test, but if I'd moved the case around at all, or pushed slightly different on the fitting when I put my video card in, I would have flooded coolant all over. I'd like to see it 10-20$ cheaper, it's simple for what it is, but you're buying it for insurance.

Defective
I got a defective hose, because there is no thread on one side and I can't screw it on, so I have to return it!

It's somewhat worth it
Pretty cool pump but it's expensive

If you need to pressure test your water cooling before filling (which I’d recommend) then you won’t find better than this for the price. Absolutely solid piece of kit

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...

Sin duda en un bue producto y muy necesario para la instalacion de tu refrigeracion liquida en tu setup, principalmente con tubo rigido, esta construida con muy buen material, es alto su precio, deberia de valer la mitad, pero tienes que pagar lo que vale, es forzoso tenerla si no quieres dañar tu setup.
