Xps3-0 review - EOTech XPS3 Transverse Red Dot Sight

This is my first Eotech sight. I originally wanted an Aimpoint, but I liked the open view and easy two-eyes open useability of the Eotech.
The reticle takes some getting used to as it is not clearly defined, but is instead made up of rather large 'pixel's. The center point on mine looks rather more like a triangle. These effects are minimised when using the sight properly and maintaining focus on the target however.
My big complaint is that the sight won't stay tight to the rail. I have the XPS3-0 installed on a late model Ruger Mini-14 ranch rifle, and every two or three shots the sight is loose. Sure I could loctite the screw, but then the whole reason for having an easily removed and replaced sight is negated. I guess I have to add, "stop after every three shots and retighten sight" to my shooting scenarios. Maybe I'll sell this and get an Aimpoint.
Cons: Sight loosens after two or three firings of .223
