Has anyone seen / tried this?

Seems interesting you use a "pen grip" (fingertips close together).
Few buttons though (3).

palm or claw grip?

I have used this mouse for 3 months now! Really helped with my discomfort in my arm and shoulder. Def worth a try. It has more than 3 buttons. Its got 3 DPI settings and left /right hand button.

Those buttons don't count. I'm talking about buttons that can do actions on the computer, like buttons 6-7 (typically horizontal scroll), 8, 9, 10, etc.
Anyway, can you tell me how hard it is to press the left, right and middle (scrollwheel) button compared to say a standard microsoft mouse (which has lighter buttons than most). Even better if you can use the highly scientific and yet easy to find Rip-O-Meter tool: http://geekhack.org/showwiki.php?title=Island:6189

I read somewhere but can't remember the webpage that the DXT uses the same microswitches as Logitech etc (think it's Omron)
I have a Correx Gramm meter from uni which gave the following results.
Left click DXT (just above the scroll wheel) 75-80 grams.
Right Click DXT (Just below the scroll wheel) 75-80 grams.
Middle click DXT (not very accurate test) 90-100 grams. ( does not sound like the same switch as the left and right click)
Tested my standard Logitech mouse which gave the following results.
Left & right click (next to scroll wheel) 75-80 grams.
Middle click (not very accurate test) 90 grams.
For you info, i use the left/right handed button all the time which is why i bought the mouse.

Good that there is some non-sensitive area above the "left" mouse button. I find that with the Evoluent, I tend to revert to hold my index finger on top of the mouse. I suppose that with the DXT, I am prevented from doing that.
Middle click DXT (not very accurate test) 90-100 grams. ( does not sound like the same switch as the left and right click)
Inside most mice with a scroll wheel, the switch for middle-click is not under the wheel, but on the side of it, under one end of the wheel's axis. The other end of the axis is fixed.
Because the axis is pressed in the middle, there is lever action that increases the force needed to actuate the switch at the expense of travel.
Some mice -- especially the tilt-wheel mice -- have the scroll wheel in a cradle, with the switch in front of or behind the cradle.

Oh, wonderful, thank you so much! And welcome to Geekhack!

Hmm, looks like there are different Correx meters depending on the range of forces you need to measure. The one that goes from 10-100 cN seems perfect for keyboard/mice measurements!
Amazon has something sorta similar for $156, I searched for dynamometer gauge:
http://www.amazon.com/GD-25-Gauge-Dynamometer-30-250-grams/dp/B00481TFFI/
these things come in different names, dynamometer gauge, push/pull tension gauge, pressure gauge, force gauge etc. Rip-O-Meter seems more of a standard :-)

A $10 roll of nickels is also a lot cheaper than a $250 Correx.
a $10 roll of nickels would be huge. how about five $2 rolls?
-
We've veered off topic, what do you all think about this vertical mouse? I like the fact it has a slim grip, seems well suited for fine work.
-
Heh... No, you got banned for spamming about it!
-
As I said I love this mouse. You can really fly around the screen with tiny finger movements instead of large whole arm movements which reduce accuracy.
The forces are perfect for me as it gives good tactile feedback!
The one downside is there is not a wireless version yet and the price! I assume the price will come down in the future?
It's got some good feedback on Amazon.co.uk - http://www.amazon.co.uk/product-reviews/B003ZK73WK/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1
