Surpassed my expectations right out of the box!
I just received this unit and have only had time to bench-test it with air so far, but I felt compelled to leave an early review because I am so impressed. First off, the packaging is excellent. The box art is non-existent, but the actual protection is top-tier. It comes in a premium, sturdy box with high-quality support material, ensuring it arrives in perfect condition. The real surprise came when I pulled the unit out. The fit and finish are absolutely superior. Iโve bought similar units for four times this price that didnโt look or feel this well-made. It feels rugged and durable. It also comes fully equipped with a an inline switch, an LED indicator light, a fused connection, and various hardware including Teflon tape, which saves a lot of installation hassle. (Full disclosure: I'm sitting here writing this and completely blanking on the exact mounting hardware style it uses, but the build itself is solid!) I hooked it up to 12V power and air on my test bench, and it worked flawlessly. Based on how well it handled the bench test, I have zero doubts it will perform just as perfectly once fully installed. Iโm actually so happy with it that Iโm considering buying four more. I plan to keep two in the trailer and two in the shop as spares. At this price and quality, you really can't go wrongโand you never know when you or a buddy might need one. Highly recommended!

Leaks like crazy and won't seal
I finally got around to installing it today and the thing leaks like crazy and unfortunately it was just a waste of money because it's to late to send it back.

You are not installing it correctly
There is nothing wrong with this product most of the write is condemning for leaks. You guys are not installing the brass fitting. This fitting has to be installed to keep the brake fluid from leaking. It is inverted flare to the brake line.

Line adaptors are expensive but worth it.
A quality product for the price,, works amazing. There was a couple of hickups.. first off no Instructions for setting this up. No markings on unit to identify what lines went where.. Got that figured out.. Then the big one.. No line fittings to put lines in. ANd they were metric to standard for my application and the adaptors cost more than the unit itself. ALSO had to go to a specialty show for parts as its not an AUTOMOTIVE application in the US.Still a good set up but be aware of those fittings

Honestly good for the price, if you have the right parts.
If you donโt do it like this. Itโll leak no matter what. Cost me about 15 dollars total to get the fittings and line. It would be well worth the money if the right fittings came included but I would not recommend this to someone who has never done break lines before, it would be awesome if the owner of the listing got back with me for suggestions. This thing is awesome if you got the know how.

So far so good
Just installed, installation went fine. Noticed a few people are talking about the inlet port hole being misaligned. Just want to clarify, that misalignment is completely irrelevant. The ports on the housing are NOT flare fittings, you cant thread your brake line directly into the part. You have to thread in the appropriate adapter which is a tapered NPT thread first. The adapter, being sealed by the thread not the flare means the hole in the inlet housing doesnt matter at all if its not aligned. Hence why they supply Teflon tape with the kit. Hope this helps! PS fun fact: you can also see the misaligned hole in the instructions image.
