It works very well for eye relief. Depending on your marker setup, you might need a riser under it to give you goggles clearance since it doesn't have rings, it's a built in mounting system and it sits pretty low. With my DAM and the HHA, I have plenty of clearance.
The rangefinder makes a huge difference. I started with the Vendetta but it was a little inconvenient and only went out to about 70 yards.
Here's a pic of me and my ghillie from supergame. I don't' think anyone else looked very similar....lol.
