Do you use your thumb to move the marble?

You can use your thumb on the left side opening of the mouse or use your four other fingers on the right side opening.

hi marina. it can be used, but it's much easier and more complete (at least for me) to use the right side of the trackball. just more exposed surface of the ball to use. maybe it would be a better idea to use it as a brake to stop the movement. a tempting thought since one of the buttons is right below it. playing with it as i write this, there is just more control with the fingers. i'm going to take a guess and say the thumb hole is to push out the ball for cleaning rather then moving the cursor. if you're thinking about getting one, remember, this technology is a bunch of years old, so the options to use it on current machines might be limited. you may need to get a gender converter to use it. ps2 plug to what is used for mice and keyboards today, meaning usb ports. i think the software is still valid up at logitech but i suggest you check to see the downloads on site. don't know what you are going to use it for, but for word processing, spreadsheets, it is tops. gaming, cad, you might want to think about it. anywho, this was rated the best trackball of the year when it came out, then one year later it was gone. amazon, ebay, might cost you a bit more then the 65-70 dollar original price when it came out. hope this helps. (i have four, two for backup, so i guess i like the thing)

Yes. I owned this item a few years ago, so I'm no expert at it any more. (I did not get one when they first came out in the Jurassic Era.)

i used my whole hand. thumb on the bottom groove with the open hole, and my fingertips resting on the top of the ball. it allowed the most incredibly precise positioning.

Not at all, it works great. You can do 4 fingers at a time and then both thumbs, still very quick and effective.

Not really. I press the left button the my thumb, which is the strongest finger in the hand. I feel it's alright. And for the ball, I use the index and middle fingers to control, so you don't have to change your position at all.

Right thumb would control,forward,back,left and right. If you place remote on table,you could use index finger to control it.

I was tempted to answer "I don't know." There's not that much comparison. The base on Marble Mouse is larger, but the marble doesn't call for movement as the trackball does. My vote is in favor of Marble.

It includes a fake thumb for at least one of the tricks. No sure about the thumb disappearing tho.

I do not have marble but see no reason why not to as it is a very light machine and it has the soft pads that fit over the brushes so it should not scratch the marble. Be sure to have the area free of dirt and grit before use.

I only do thumbs separately. It is large enough to do all 5, but have been afraid to try it.

There are special toggle like mechanisms that I used to attach to the cultured marble and drywall. You have to drill a large enough hole to pass the mechanism threw with a hole saw. I do not remember the size maybe 1 3/8" ?? I weigh 300+ lbs. and I pushed on it and it did not move. Good product!!!!

Not easily. I usually 'catch' the lip of the ring with pongs of a fork and try to maneuver it, or just get some warm fingers. its a bit tricky. there might be a better option/tool but I havent figured it out yet.

Yes you can. I don't know why someone would say you can't. You must use your finger or thumb.

I only use it on a middle finger. I don't know how it would work on your thumb. if it were me I woulduse a thumb splint. so sorry I can't be more help to you

Yes. The marble base is so extremely heavy that it pretty much stays glued to all surfaces.

No, I would not use it on marble. Marble is softer and more pourous than even granite.

No. It will work fine for most things but marble can crack if too much heat is applied.

Did you Tap the screen and then hold it and drag you finger in direction you wanted to move it. This could take a couple of times and getting use to. A little move of finger is a big move.
