I got to throw the M1 and M4 today (both 180g) and was pleasantly surprised. Conditions were sunny, 72 degrees, with almost no wind (2 - 5 mph).
The M1 is between a really beefy Roc and a Gator for me (I've never thrown a Drone). If you power it up, it's nice and straight with a healthy fade. If you throw it powered down, it's pretty overstable. Surprisingly good glide despite the overstable tendencies.
The M4 fit me perfectly - instant bag spot. It's mildly understable as it will go right before tracking straight and finishing with almost no fade, but not your typical understable. I throw a fuse or stingray for that slot and it's not even remotely like them as it won't keep going right without releasing on an anhyzer or really ripping into it. It's glide was incredible, even on powered down throws. Great point and shoot disc, will hold a soft hyzer or anhyzer, really a nice complement to my workhorse 2FR Buzzzes but longer with less effort. Easily 30 feet more distance with similar effort.
I've also tried their D1 and D4 and like those as well. Other than the silly naming and PR joke of Prodigy so far, I find their plastic to be superior (GREAT grip and glide) to anything on the market. Now I'm curious to see if the plastic will keep the characteristics once it beats in, and how they will throw then. So far, as a skeptical buyer, I've been very impressed which is not easy to do.
