Yes it is! I like it. Cheaper than some of the aftermarket options too, even with the relays and digital controller. It pushes more air than a lot of aftermarket fans too, ~3,500 cfm on low and ~5,000 cfm on high, depending on who you ask. I've only had the high speed kick on a couple of times, this summer was lousy and we had a few 105+*f days where I was out and about in traffic. And it's an OE set up, I know Ford tested the crap out of it and they go 100,000 plus miles. And if it craps out there's at least a chance I can get some of the parts locally.
You do need to invest in some other electrical upgrades though. I run mine with a 100 amp alternator, and I would suggest an amp gauge bypass. I've been running mine without one so far, I converted a stock amp gauge over to a voltmeter to swap in but haven't done the install and bypass yet. I do run it with its own relays, and I have everything attached to a continuous duty relay already as the pictures in my thread show. But I think those upgrades go along with any fan set up that will push enough CFM to be useful, big CFM means a big draw, that's just the way it is.
