One Finger Mouse, USB, Blac

I have been having problems with carpel tunnnel for years.

I found this product and got releif.

However! This product does take some getting used to, you must teach your self to use it.

You also do not hold it as in the picture. Correct way to hold it is with your middle finger thru the center, using your thumb for the track ball and your middle finger for the center button which you should set up as your right click. It works equally well right or left handed. I work lefty but did not have to re-set the button settings; righty settings work for either hand.

Buy it an play with it, it is worth learning to use it.

This is a fine device, probably the most usable of the ultra-portable trackballs. The ball sensor, while wheel based, is adequately sensitive, and easily cleaned.

Unfortunately it's design requires you to press firmly on the left-click button to hold the device steady, there is no way to grip it securely and so the device wobbles a bit while using, and can result in accidental clicking. With the casing extending further back into the palm it would be easier to grip securely without having to hold firmly on the control surfaces.

takes little time to get used to. I use it for my laptop at home. i have the 4D model: left mouse button is in the ring (not too sensitive for inadvertant clicks), right mouse button is on top at the right, left button on top is for scroll mode.

shopping or browsing is best.

if you have to type, it is possible while holding it.

improvements:

1. a little more plastic on the bottom base back part to wrap the middle finger around more firmly.

2. if you hold it tilting back or side, the ball needs to be heavier so it doesn't pop up when you let go and move the cursor right before you click. it is hard to keep the ball still with your thumb on it while clicking because it will move the cursor.

3. after 5 hrs or a weeks worth, no real skipping, but probably will need to be cleaned more than a mouse

The One Finger Mouse (actually a trackball) is designed for those who need a small, inexpensive and durable hand-held pointing device. If you have a poor quality, or no touchpad, it is a godsend.

I found mine to be easy to master, and wonderful for cramped situations where there is no desk space for a mouse, especially in a car or aircraft, or when luggage space is at a premium. In such circumstances it is better than a small wireless mouse, if for no other reason than the USB cable becomes an asset for retrieving a dropped device from under the seat!

Some reported difficulty with the grip, but with a little experimentation, I found that I could hold it firmly enough; it is more comfortable for some to use the second finger rather than the index finger to operate the trigger-like left-click button, which may bring the thumb in better alignment with the controls on the top. I don't think there is a "best" or "correct" grip. In fact, the ability to use different grips is an ergonomic advantage.

The trackball has one other very important asset in close quarters: it can be easily used in any orientation, in contrast to a mouse which is very difficult to use unless aligned squarely with the computer.

I had no difficulty operating the device, except that one has to put it down to touch type (one can continue to hold it while pecking simple entries). For serious typing I reluctantly defaulted to my inferior touch pad. I have since found that the Finger Mouse can be laid on its side on a desktop (on a non-slip surface like a mouse pad), and easily operated without picking it up in the course of prolonged typing. Now I use it in combination with the touchpad.

This trackball is GREAT for browsing. The left button invokes an omnidirectional scroll function.

Certainly a number of good suggestions for improvement have been made, which would result in a superior, but more expensive device. As there are no other satisfactory miniature, hand held trackballs on the market, and only one (expensive) desktop model to my knowledge, I think an improved Finger Mouse model could be successful. But don't hold your breath, get this one, it's plenty good enough!

For travel, the One Finger Mouse is a uniquely adequate and satisfactory solution. And if you lose this little gem, it's cheap to replace! I think I'll buy a spare.

The spare arrived boxed and named the Off-Table Track Mouse, available in PS2 or USB versions; compatibility with Vista is not stated.

It's a 5 Star in its price range and against anything else!

I was looking to give my right wrist a break (I use a marble man from logitech) & this looked great for left hand. Marbleman is great, better then any normal mouse for anyone who has to be careful with their wrists. I am also looking to increase sensitivity & more motor use for my left hand.

This was pretty easy to get used to, a little cumbersome but not bad. The reason I am returning it is because each time you want to use your hand to type, you have to put it down, disentangle your hand from it then type which takes a few seconds for someone impatient like me.
