Ergonomy questions about some fingertip mice

post #1 of 9
Thread Starter 
Hi everyone,
I usually don't open threads but I've searched the forums for some time (and I don't have anywhere to check this stuff in person) so here I am. Usually people talk about palm or claw grip, but I hold my mouse in what I'd say a completely fingertip way: my palm almost never touches the mouse.

My Razer Krait is causing RSI for quite some time now and I've finally got a bit of cash to get a new mouse. I'm practically interested in 3 mice: Razer Salmosa, Razer Abyssus and CM Spawn (note: I don't have enough cash for a Logitech G9 and also think it's too heavy for me, Kinzu is also a "no" cause of it's high prediction and Zowie is unavailable in my country).

The first question I have is: do Abyssus and Salmosa have slanted sides (wider at the top, narrower at the bottom) like Krait does or do they have straight sides like Logitech G3 for instance? Krait's specification says it is 60.5mm wide but since it's sides are slanted I hold it at ~50mm width and it's too narrow for me. That shape is one of the leading causes of RSI in my hand and if Abyssus and Salmosa are like that as well, their 3mm more in specification width means practically nothing to me.

The second question is: is Spawn too wide? I'm used to this narrow shape of Krait and since I hold and move the mouse with my thumb and pinky (forwards-backwards movement as well, my wrist doesn't slide nor lifts off) I fear I will lose that kind of mobility if the mouse is too wide, but maybe that's just a misconception on my part.

The third question is: do Abyssus and Salmosa have glossy sides like Krait or rubberized like Logi G3? My Krait slides a bit sometimes so I have to grip it even harder making my hand hurt more.

And the last question is: Is Spawn too heavy? From what I've found, my Krait is 5g lighter than Spawn but sometimes it feels too heavy for my style of holding it when I lift it off the pad. I'm just not sure if the weight is really the problem or it is the length of the mouse because I'm beginning to think the problem is that I hold my mouse so far back that when I try to lift it off - the front part of the mouse plus cable make me feel it is too heavy. Also, I lift the mouse with my thumb and pinky and just slightly use the ring finger for balance (at least on Krait).

Some more notes: my hand is 19-20cm from wrist to top of the middle finger, I do not hold my middle finger on the scroll button but on the right click button, I use a qck mini mousepad since I have a small desktop area and I almost only play Modern Warfare 2 and Starcraft 2.

Thanks for your time and responses!

p.s. A non-ergonomy question: Is Salmosa's prediction as hard as Krait's? I can feel it's downsides in MW2.

I can't really comment on the Salmosa or Abyssus, as I haven't had either of those mice, but I am in the same boat as you regarding small/narrow mice, and at risk for getting RSI issues. My hands are 21 cm from wrist to middle fingertip, and 21 cm measured with a tape wrapped around the middle of my hand, so my hands are slightly larger than yours. I am used to wider palm grip mice, and the Naos 5000, Ikari and G5/MX518 were great for that, but I bought the Spawn, because I was interested in the new optical sensor in it, and was curious to try a fingertip style grip mouse, that was wide enough that I wouldn't cramp up on it. I also can't use mice much over 40 mm height, or I get cramps in the back of my hand. I was pleasantly surprised with the Spawn, and the transition to it was easy and natural. My hand drapes quite relaxed over it, and there is no strain gripping or lifting it. My thumb is on the left side of course, my index and middle fingers are on the main buttons, the ring finger on the right side ledge, and my pinky on the right side. I can easily lift the Spawn using either ring finger, pinky, or both. Actually, I think this is almost the only way for me to comfortably grip this mouse, and I would consider it to be a fingertip grip, but I suppose you could use a claw grip as well. The width of the Spawn is actually what makes it relaxing to hold for me, I'm sure I would get cramps with anything much narrower (the Logitech LX3 mouse was the worst-ever for me ergonomically). The Spawn is definitely not too wide for me, it could even have been another 10-15 mm wider and still been fine. Based on your preferred grip style and hand size, I think the Spawn would probably be a very good match for you.

I can personally tell you that salmosa was the best mouse I have ever used as far as sensor and mouse shape go. I stopped using the salmosa when my first one finally gave in and I went to go buy another one and I found out they had discontinued them. I later bought a g9x and have been happy with it but not as much as I was with the salmosa. I just found out recently though they only discontinued them in the U.S. only and still market and sell them in Korea for around 20.00$ USD so I ordered 2 of them last week.

The salmosa for me is the perfect mouse IMO. 800 dpi and rate switches on the bottom for driverless use and its super light weight for fingertip use.

Edit: Also I have tried the abyssus, it is far from the salmosa even though they have the same shape. Mine had the obvious jitter issues that most of the ones still do.

Abyssus and salmosa does have slanted sides

Cm storm spawn is a bid wide but its only so the ring and pinky have a place to rest which is the first i ever seen in a clawgrip mouse and works out really well

Abyssus and Salmosa does have glossy sides

Based on what you wrote I think you would be more happy getting the zowie mico

I did have both cm storm spawn, abyssus, salmosa and the mico

the abyssus has slanted sides so you can lift it with your thumb and ring finger with ease. the sides are glossy but they actually arent that slippery unless your fingers get really really sweaty. we grip mice the same way, and i can tell you the abyssus is awesome for sc2/rts games.

Try the roccat kova or kova [+] a go. Its wider than a krait, not glossy and okay in comfort.

Kova is a bit on the low side of build quality. It squeaks if you hold it too hard and so on. Can't comment on the kova [+] much, since i dont have it, but it's the same shape.

Another safe bet would be the WMO. Its got only 400 dpi, but its really good shape wise.

had the old kova for a short while, and the build quality isnt good. it tends to squeak alot, the glue from the rubber side grips would seep out sometimes, and even the shell of the mouse itself unattached from the side. it was a frickin mess. the shape was good though. i hope they improved the build quality on the plus version.

Yeah, tbh it wasnt good in the build quality department. But neither was the original kone...

But the kone [+] is miles better, so perhaps the kova + is better aswell. Dunno. Buts it s agood shape and sensor is OK.

Another mouse thats ok for finger grip/claw is the A4TECH 760H. Avago 3060 sensor and good ergonomics

Thanks for your responses guys!

@ElectricDelta: I'm glad you answered since I've seen you mention you use a fingertip grip on Spawn in some other topic.

@Buckmoney: Could you also tell me how hard is Salmosa's prediction?

@HaiiYaa: Thanks for your responses! Unfortunatelly Zowie is unavailable in my country and even if it was I feel that the Mico with his 58mm would be too narrow for me. :/ Btw, do you remember if Salmosa had lots of prediction?

@Spade616: I understand the point in making the sides slanted but it was mainly that shape (several aspects of it) that caused my RSI. Also my fingers do slip on glossy sides...

@2shellbonus: While Spawn, Salmosa and Abyssus are all around 30€ here, Kova is around 45€. Also considering the fact that it has the poorest build quality of them all and that it is the longest and heaviest I think I'll pass...
