I have the E11 and since saturday afternoon also the MC11. Absolutely love the E11 because of how cheap it is and it's simplicity. Controls and handles very well and it's super light and feels sturdy. No flicker, wobble, rattle or play of any kind.
The MC11 is nice and (almost) one of a kind. The button was an absolute disappointment though, up to the point where I contemplated sending it back for a refund, which I'm still considering. It's not realistically possible to change the light level (or mode) without eventually injuring your finger. Thank god it has mode memory and I can pretty much leave it on the middle mode, or it'd be useless altogether.
For that price, I'd rather add another edc style body, or get one of the ZebraLights (which that store doesn't carry unfortunately).
Based on that, I think the MC11 was my last fenix. Next light is an EagleTac D25C, and I'm seriously contemplating either a Sunwayman M20A or M11R. The interface of the M series looks amazing. I'd love a V, but they waste too much power on the variable power.
