Good answers. Thought I'd chime in with my 2 cents (or in this case, 2 benjamins).
1.) I know that we are a little different, having gone with the idea of allowing set up of different 'macro pages'. But this allows you to accomplish mode changes faster on the Viking macro controller than with any other rapidfire controller on the market.
All of the other rapidfire controllers to-date require that you press and hold a tac switch, and wait while you watch the LED flash through all modes. All the companies pride themselves somewhat like this: "You want to buy our AwesomeModz AwesomeBlaster 9000 because it's a 10 mode mod!" "Oh yeah, our mod is 12 modes!" More modes is NOT better! If your mod has 12 modes - guess what - you'll have to sit there holding a tac switch all day while you count off flashes on the LED... 1... 2... 3... 4.... zzz....
With The Viking macro controller, you can set up rapidfire at 10 shots per second on the blue page, and set up jitter mod on the red page. Then just tap the tac switch one time to change from the red page to the blue page. No delay, no counting LED's flashing. Just tap and bam, you're ready to go with the other mode. Or set up multiple pages, the only difference is you have to tap the tac switch for as many pages as you want to skip. You're only limited by how fast you can tap the tac switch.
Once you wrap your head around the idea of using pages instead of modes, you will changing between modes faster than ever.
3.) Free macro editing software. Free software updates for life. Honest support forums with great customers. Free support ticketing system. Free on-line macro library for sharing all the greatest glitches. User-programmable LED's - nobody offers this. The Viking Macro controller isn't for everybody - you may not need or care about all these features - but if you are a hard core gamer, this is the controller for you. We sell the best, period. Once you pay the $200, you're done.
4.) Nobody offers a lifetime warranty on controllers. However, if there are defects in manufacturing of the controller (by Microsoft), or defects in our mod chip or the mod chip installation, we repair any problems free for 90 days. 99.99% of equipment problems will show up in the first 90 days. (What we don't cover is customer abuse or tampering/removing the warranty sticker, spilling soda pop and food in the controller, etc.).
[If you have a legitimate gripe about your mod after the 90 days, please contact us. In most cases, if it's not due to regular wear n' tear, we'll make the repairs. Especially if it's a failure of the mod chip or mod chip installation itself. Our hardware should be good for life. But we can't offer a lifetime warranty, because customers would take advantage of us and expect us to replace their mod for free, every year, for life. And it's just not realistic to expect that this controller won't wear out from regular gameplay.]
