It looks like a bloody mobile phone now.
Seriously, there is a line between playing FPS games for fun and fanatical playing them.
I'd say no, don't waste your money on stuff that doesn't feel alright in your hand with features that you wont use. Get a normal mouse with LMB, MMB and RMB, those three are all you need.
Besides, the 1 to 0 buttons are close to your WASD keys anyway.
Well, for FPS I can't see why you'd need hotkeys at all, but then again, I don't play much FPS other than for fun, and I do fine with just WASD and a regular mouse anyway.. but when it comes to games where you actually need hotkeys, it's different.
I don't know how it feels in my hand, so I was hoping someone had experience with that mouse - I will utilize the hotkeys to the maximum (you get more hotkeys by combining with, for instance, CTRL and 1-12 hotkey), so it is definitely useful! Though I've never had a Razer so I don't know how the quality is, and most of all, the hotkeys seem a bit tight.
LMB, WHEEL and RMB is definitely not enough for me, once you've tried a mouse with BACK and FORTH, you don't go for another, regular mouse. Then also apply sensitivity levels, and you're almost there.. the only thing missing is a few hotkeys. 1-0 is way too far from WASD, you can't click 5 while still maintaining a right turn, and not 1 doing a left turn (well, it can be done of course, but it's not a good solution). Besides, not all games have WASD movement - *cough* DotA *cough* .. so you're stuck with ARROWKEYS, which is even worse.. with CTRL, 0 and SHIFT the only really useful hotkeys - and these are usually occupied for more important things. Thereby leaving the only good solution to have hotkeys on your mouse, or buying a gaming keyboard (those small ones) and assign the arrow-keys to the middle of it and have the hotkeys around..
