I purchased this with a lot of excitement as bleeding brakes on some cars can be quite difficult in getting all the air out, and the reviews here were good.
I was unable to use it however on the first car I tried, which was a 2017 Kia Forte. None of the standard adapters fit, except for one that came close (one that used an o-ring and fit into the master cylinder filler neck). Seemed loose in the neck and I don't know that it would have worked, but I never found out because the plastic tabs on it would not hold the cap securely (they bent out). Also, all the connectors on the caps for the hose go straight, and in this case, there was no way for me to get the hose on because the cowl was in the way. It was impossible to use the universal cap because of the same issue. That's not the fault of the tool per say, but it would be better if all the connectors were at right angles to the cap so it could work in more situations. Many cars have the master cylinder tucked in under the cowl.
The caps by the way were not finished well. Many had plastic hanging off from where they were threaded. Something to watch out for. Had I not been looking, I could have easily ended up with a plugged master cylinder. I did not find a manual included either and had to find it on-line. The recovery bottle also leaked at the top (I used it when I manually bled the brakes with a helper).
I'm keeping the tool though in the hope that I can do a reverse flush in cases like this by coming up with a hookup for the bleeder screw that will be air tight (another product feature that might be nice as an option).
Looks like it would have done the job, but some things to watch out for before you buy.
