Just grabbed one. Boy it's a bloody big mouse, and I thought I like big mice enough =/. I just played with it for a few hours now and can't really pinpoint the pros and cons but roughly:-
Pros
-- It's actually cheap (for the moment)! I got mine for NZD90 (~USD60) and I think the 25% Microsoft discount is gonna be until January 31st. Mine is OEM but who give a sheep at fancy boxes.
-- Handy on-the-fly DPI changer.
-- The wheel is a tad weird (it's metal), but actually works.
-- All buttons are easy to reach; the vertical side-buttons is a nice twist.
-- LCD display for DPI.
-- Weight container doubles as anchor.
-- Comfortable for those with medium-big hands.
-- Slick and beautiful. They say it's based on Master Chief, but I see more Transformer
.
Cons
-- Definitely not for average Asian (I am one
). Fortunately it fits me quite well.
-- Definitely not for lefties.
-- Only 2000dpi maximum.
-- Only 500Hz reports frequency.
-- With that said, this is probably not for professional gamers.
-- Lack of DPI fine-tuning.
-- Some people might hate the ever-on red lights.
-- None of the features are really revolutionary.
I've never tried the G9, but from the reactions it seems like this mouse is a tad lower in greatness compared to G9, but probably better than the G5. There's nothing wrong with this mouse, but there's not much great things either (I actually love it for the look). All in all, it's definitely worth the purchase given it's low promotional price at the moment. But because it doesn't 'wow' me at the first impression, I give it an
8.5/10.
EDIT: I didn't yet try the macros (never used any macros with any mice before), but basically you can set the macros along with a time delay for execution. I'm not sure if it's common for other mice, but it's a nice feature.
