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 USEWhy did you pick this product vs others?:OTHERS DID NOT WORK AS WELL

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.

This thing was a life saver. Just built my first water cooled PC and this pump helped me find several leaks I would’ve missed.

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.

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.

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.

worked like a charm but a bit overpriced for what it is. still helps me make sure all my fittings have a good seal every time i flush my system, and inevitably one isn't seated right.

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.
