  I actually ordered another similar mouse, but the amazon merchant [ olive ties] shipped me this one [ with the GREEN TRACK BALL] instead; sort of a bait & switch game, I guess. I used it for 15 minutes and the track ball became very im-precise and jittery. It is useless for controlling the cursor with. It is useless.

  It says model fdm-g62 on the label , made by “3d green globe company”, China. It sells on Amazon under different manufacturer names, it seems.

  I will not return it because the shipping costs to return it would be as much as the mouse cost me. I will just junk it.

  Don’t buy this, at any price.

  The identical trackball (for that is what it is) is also marketed on Amazon as the One Finger Mouse. The average of about 20 reviews for it is 3.5 stars. One should read these reviews, as the first review here is not representative.

  It is designed for those who need a small hand-held cursor control device, especially when a work surface is unavailable, as when traveling.

  A few had problems with it, either mechanical, or not liking the design, but most found it helpful for its ergonomics (repetitive motion syndrome relief), and no need for a surface to operate it. Few thought it perfect, but most were satisfied; it is the only TRACKBALL of its kind, and very inexpensive, so one can hardly expect perfection. The biggest downside to me, is that one has to put it down to touch type: then I’m forced to revert to the inferior touch pad. The trackball is GREAT for browsing, and SO much better than my touch pad.

  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. Seated at my desk, I use a large desk-top trackball for its greater precision, but for travel, or for use while standing (eg using a projection screen), the One Finger Mouse is quite adequate.

  Order this junk, and buy a new regular mouse also, when you have them both, throw away the finger mouse and use the new (regular) mouse.

  I got one for my daughter, after 10 minutes the rollers under the green ball broke (yes broke) its junk, about 5 or 10 years ago i found one that was optical not ball type, dog ate it and i havent been able to find one since. dont buy this one it is truly junk.

  I ordered this product, after a similar one I had stopped working. Its easy to use and it lets your arm rest more when you have a lot of researching or if your just surfing the net. I recommend this Item

  I already had one of these, but the vertical movement started to be less and less accurate (I had to scroll a lot to barely move the pointer)

  So I decided, “hey, It’s time to get a new one” too bad the new one already had the same issue…

  So, it’s a nice product, but the construction may be a little cheap.

  This is a fine example of the junk that China is dumping on American consumers. The first day I received the mouse the horizontal movement did not work. The USB cable will probably not stand much abuse. Overall the product is not worth more than five dollars. I have purchased a similar product in the past and was somewhat dissatisfied with the quality but this product is one step above crap.

  I had to get a mouse that I could use to prevent RSI, and my right wrist has been aching for years. I’ve tried an ergo mouse (Evoluent) but mousing still bothers me.
  
  This mouse lets me use my left or right hand in a different way, reducing repetition (and therefore RSI).
  
  Its construction is fair. Problem 1 is the trackball: it’s not optical, so the rollers don’t sense every move.
  
  Problem 2 is the primary button: pressing it requires a pinching motion against the thumb…which is operating the trackball. That causes some clicks to jump, which can lead to broken keyboards, divorces, harsh language and scared cats, especially if you’ve got a paper or presentation due and nothing seems to be going right. Curiously, this is one piece of equipment that shouldn’t be used with alcohol.
  
  Problem 3 is that it makes jumping between typing and mousing difficult, slow, deliberate, and unintuitive.
  
  If I were to improve this product I would design the button to register an unfelt trigger halfway through a click that prevents it from acknowledging trackball movement in anticipation of a “real” click. I would also update it to laser or at least optical tracking. Wireless would be kind of useful. Lastly, some way to integrate a scroll wheel would be spazztastic.
  
  I’m still using it though. The relief on my arm justifies it.

  I really like the feel of this mini trackball. Unfortunately the trigger broke after just 5 weeks of use.
