I have it on my BMW. It works great. There is still a similar looking control as you would have with a conventional system but instead of wiper speed it is basically a "sensitivity" or a "desired dryness". Here in the PNW rain can be a light mist or proper raindrops and may change minute to minute. So I just turn it on, set it to something in the middle and the wipers wipe when necessary. I rarely have to touch it again after turning it on.
Compare this to my old Toyota that just had low-med-high. Low was still moving constantly, the only intermittent was a manual "mist". This meant my wipers were running way too much even on low or I had to hit the mist every 10-20 seconds.
