This disc is somewhat disappointing. I have been throwing a M2 and started to break it in a bit too much to act as my overstable midrange. I picked up a M1 to see if it was any more stable and reliable. The M1 is very straight out of the box and is not reliable in any headwind. I wish it was much more stable than it is. Without a wind it is nice and straight with a slight fade at the end. The flight is similar to a buzzz but it does not fight the wind as well. I'm going to look around for a more overstable mid elsewhere I think. Overall, could have been much better.

Disc - 175, 400 M1

Feel - This disc is a non-beaded midrange that is fairly deep and flat. I really enjoy the feel of this disc but if you do not like the feel of deep mids then you may not like the feel of this disc. It feels similar to a buzzz os in my opinion. It feels good in the hand for both backand and forehand grips.

Flight - The M1 is not nearly as overstable as the numbers suggest. It actually has a lot of glide and a nice gradual fade at the end of the flight. It goes very straight for most of the flight and then has a nice fade. I really enjoy this disc for open shots or shots that I need to put on anhyzer and then fade back out to flat.

Overall - Nice overstable mid but not gator/justice/recluse overstability. Feels really good in the hand and I like it for something in between a straight mid and very overstable mid. 

When I got a 300 M1 in both of the mystery boxes I got it was one of the discs I was not very excited to throw...until I threw it. And it was fantastic. 
 

It is a great disc as long as you don't expect it to be something it isn't. It's not a very overstable Justice/Deflector disc. It's a beadless disc with the ability to take a lot of power while holding a line, but not turn and burn unless you torque it over really hard.

in the 300 plastic this disc for me does what other are able to make a Buzzz or Roc do. Hold a straight line with a touch of turn and a sharp but not incredibly hard fade.

I've only played 5 rounds with my(now 3) that I have, but they have already netted me many birdies and gotten out of a few tight spots.

I'm not the biggest Prodigy fan in general, but you can't deny a great disc. And the hand feel and flight of this one make it great to me. I don't know what it is but I have a hard time dialing in midranges at full power, often using discs like the Bard and Yao in that slot, and like those discs this one wants to be thrown hard and does well when you do. It's a touch faster than the Yao and not quite as hard fading as most Bards and may find a spot in my bag for a long time for shots in the 250-350 range as a result.

I absolutely love the 300 M1. The grip and feel of the 300 plastic is grippy and firm. I bag two of these. One that is slightly beat up and one that is fairly new. My beat up M1 is super straight and will not turn over. I get a little more distance out of this one but it will always finish left and and land really soft. 

I bought this to replace my rocs and have been very happy thus far.  My go to mid is a M4 or Claymore (depends on mode, I see them as the same thing).  But I always have an overstable and understable in the bag.  This is my overstable.  While I call my M4 my go to, the reality is that a ton of holes require an overstable mid.  This will fade back into the wind, and will even give me a skip sometimes.  Feels great in the hand, and I find that I get consistently more distance then I did with my rocs.  The 300s is nice because it breaks in a LOT faster than 400, letting me work this disc in and giving some options.  I don't think I would be upset if I was limited to this disc as my only mid.  

This is a fun disc. Great for short holes and long approach shots, this disc has the reliable flight pattern to come in clutch and rattle the chains.
