As you say, out of the 100% of people that buy gaming mice, 90% are Right handed, yet because there are a few other gaming mice out there your sales would be closer to that of 40% of right handers.

If make a left handed version however, you are pretty much guaranteed the full 10%
Which in turn would increase your profits by 20%

Looks to me like a good reason to bring back left handers.

But before putting affort in this sort of things it would be better to fix current product problems (e.g. DeathAdder Acceleraton).

…love your products, - “by gamers, for gamers”

One thing that has concerned me in recent years, (particularly since we’re celebrating the mouse), is why there are no fine companies, (such as yours), who have stepped up to advance the trackball. (…yes, i know, I’m a relic, a dinosaur)

While I understand that businesses prefer to provide products to burgeoning markets, there still are quite a few of us old-fashioned, old-time gamers, that prefer to utilize the best of the best gaming peripherals, ( uh, that is, the trackball), when killing an onslaught of online mouse wielding hooligans.

Throw us “old predators” a bone. I would gladly give away 10 of my mice for one solid trackball. Take an old Microsoft Trackball Explorer 1.0 and apply some of that incredible Razer engineering to it, to reestablish a position for another fine invention, - one also worthy of a 38th year anniversary.

Please understand that while we make products for gamers and love what we do, we also must run a business. In order to cover the R&D costs for any product we must sell approximately 80,000 units just to break even. In sizing the marketplace for lefties who actually play with their left hand (I’m a lefty that switched years ago) it just isn’t a good business decision to offer a second version of the DeathAdder. We do understand how you feel and offer you our sincere condolences in this matter.
