Ok, so I've been playing around with OM and he amazing! Far better than I ever thought and well worth the decision to actually get him.
The Prime torso is beautifully fixed and the color scheme is nice. The robot mode head is AMAZING and I love it to no end. The combined mode head is pretty awesome too.
The limbs have very nice paint jobs to me and the overall aesthetic looks pretty stunning. The fact that you can place the prowl and Sunstreaker weapons in so he has shoulder cannons is pretty cool too.
Overall I really do like him! really do!! He is a great figure and honestly worth the investment. I will be keeping him in the configuration from CW4: Ironhide and Mirage as legs, Streaker and Prowl as arms. Helps him look much different from Menasor and overall really good.
I rate him pretty high. If you can, pick him up! great overall figure
