There are two other threads here that I know of with additional info. I'm probably going to start a third when my DP Pro gets some range time this weekend.
As a teaser, here is my DP Pro in two different setups:
1. Used as a primary up on the top of the upper receiver in an ADM AD-TR QD mount with Leupold riser. This produces an absolute co-witness. Minor modification of the Leupold riser was necessary to make it work with the AD-TR.
2. Used as a secondary in 45 degree offset with a scope.
I do like this optic very much. It has a good bit larger screen and field of view compared to most of the small reflex red dots. It is motion activated, so it wakes up instantly when you pick up the rifle, making it ready 24/7/365 with no buttons to push, knobs to turn or other extra steps under stress. It shuts off after being stationary for 5 minutes, then wakes up again when next picked up, returning to its same intensity setting. Battery is top mounted so that it is easily replaced without having to remove the optic and risk loss of zero. If battery life is like the motion activated Firedot on my Leupold VX-R scope, it should last for years. I'm still using the original battery in the scope after three years. It appears to be quite ruggedly constructed. Only time will tell.
FWIW, I opted for the 7.5 MOA triangle for quick target acquisition. The fine point at the top should make a good aiming point for shooting farther out. Range report will follow in a new thread.
