You might prefer buying from them, same price as EBB with the shipping, but MUCH better service, from what I've got so far:

Put shortly: it's a great optic.
The only real con is that it's 4X fixed.
What has put me off from buying one is that 4X is quite a lot... but I'd buy one in a heartbeat if there was a docter sight mount available for it.
