    • 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. ... show more

    • 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. ... show more

    • Great
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.
