They are not so good, but won't consider them as bad.
Basically, some time sensor considered bad having many factor, 1 of the problem of kinzu and kana are they are not compatible with all surfaces and work well. Therefore if you using them with a proper suitable surface, might solve certain problem.

Shape and comfort-ness wise, just individual personal preference.

There are lots of fps gamer still using IME 3.0 which they think suitable their palm the best, just maybe not so active in forum only.

Added on June 12, 2012, 10:23 pmAny problem with Ikari laser? Why looking for optical sensor?

Added on June 12, 2012, 10:26 pmBasically all of them are different, how can we compare them.

Sensei is ambidextrous, kone+ is ergonomic, g700 is wireless, G500 is not in the same price range with another 3, that's why i will say they are totally different.

For me, no doubt, their sensors are great. Precision, dpi, speed, every thing basically good.
But not for me, I still prefer ergonomic, waiting SS to release another imba mouse which can overtake Ikari.

The last problem you mentioned I think most people refer it as "jitter" issue, IMHO, it occur more on Ikari optical.
Btw, I think you may try different mouse pad may solve the problem. (in detail, maybe check at mouse pad forum looking for expert)

It is over sensitive but is due to the imprecision of the sensor. As mentioned, more occurrence in optical sensor.
Currently I using my second Ikari Laser on 9HD having no any jitter issue.

Kova is ambidextrous, Deathadder is ergonomic, shape wise, not comparable simply personal preference.

Sensor wise, both will be medium end product, should satisfy most of the users.

PS: if you are palm grip user and concern more on fps, go for DA, otherwise (mmo and strategy gamer), fingertip grip, get Kova, or maybe Razer, Abbysus.
Deathadder just too big for some small palm user.

If I not mistaken MX518 is discontinued.
There is another logitech mouse very similar to MX 518 and clearly stated by Logitech which is replacement for MX518.

I never doubt IME 3.0 whether a good mouse, but personally feel that some of other models are good alternative for IME 3.0 in terms of shape, sensors and etc. Just wonder why you very insist to have an IME as spare mouse.

Comfort wise just your on preference based on your gripping style and palm size and shape. If possible get your hand or some demo or browsing unit in lowyat plaza.

Maybe you think that the LED light on DA is nice, but for me, the light is bit unnecessary and I make it always off. The reason is because DA itself using infrared sensor which is releasing quite large amount of hit, with the led light on then is hotter cause more sweat from your hand and actually killing the rubber surface and make it peel off faster.

As you like DA so much, personally believe naga shape will satisfy you very well.

I didn't try to use any of the thumb button from any of my mouse.
I simply meant for the shape. PS: the thumb button for naga just too tough and hard to press for me. I won't use any of them.

Rare case, btw, Ikari laser or optical? What you meant by stop working with laser still on??

If you using Ikari laser, there should be no any visible light from the sensor.
That's the reason I assume you talking about Ikari optical.

It's quite common that if some time some pulse input or some error signal (can cause by improper surface used or many other facotrs) within the mouse system cause the cursor sprint to the corner of screen, but usually that doesn't need to re plug the mouse. As your case, you need to unplug the mouse (in other way, you are shutting down the mouse power), I doubt something wrong with the board.

If still under warranty, maybe need to send for RMA if it occur frequently.

What you described definitely lead to ambidextrous mouse.
Steelseries Sensei, Razer Taipan are the best I can think about.

Added on July 9, 2012, 8:12 pmI'm not sure whether all model from from Razer and Steelseries having same loud click sound, but few of their products with me are quite noisy initially before I get used to it.

Are you actually looking for gaming mouse? heavy gamer?? most of the microsoft wireless desktop set or mouse having quite quiet click.

Very true, you won't know until you really try it.

I can either palm grip or claw grip my Ikari Laser.

PS: to whom who may concern;
Although you like g9x, I personally don't recommend you that mouse, it just cost you bomb for nothing.

I never meant that is a bad built mouse or something wrong with the mouse, just it's price doesn't match it price.

In short, not worthy.

According to what we have in the market, I will recommend Razer Taipan and Sensei raw or MLG.

Of cause it was officially released, I think it is already available since today I saw all IT brochure or catalogue displaying taipan.

I think no matter how was the palm size or the mouse size still can change the grip style.

Let say a small palm player using DA, he can just hold the back parts of the mice just that not so recommended.

Myself having not very long finger but wide palm, so I consider myself semi palm grip on Imperator since the mouse is not wide enough.

Yea, I guess you and me having very similar palm shape, Ikari still the best mouse I ever had.
PS: new naga with extra side panel to exhange, one of it having similar pinky rest like Ikari, i guess you like that as well.

All the thumbs button of Naga are rubber coated, put on any of those keys will not feel slippery and won't clicked any of them accidentally because the buttons itself are quite tough.

The button really quite tough, for me is like although I want use it also hard.

Anyway all the buttons can be disable.
