This mouse comes as advertised and operates as advertised. I'm a trackball kind of guy and I surf the web a lot. I got this so I could reduce repetitive stress on my hands and forearms and maintain better posture while surfing. This device is ambidextrous and allows the user to sit in many positions or to stand.

That being said, I'm left unimpressed. I realize there has to be some play to allow the ball to roll freely but this trackball is twitchy, it works best when horizontal, less so when at any other angle. It's also unforgiving in that any fingerprint residue will cause the cursor to jump all over the place. The trigger replaces the left mouse button; the left button accesses the scroll feature. I have to remove my thumb from the ball to depress the trigger because the chassis is so small that moves in my hand and rolls the ball against my thumb which of course moves the cursor. The device is light so when placed on the table the weight of the usb cable is enough to drag it. This makes it awkward to perform any keyboard functions that require two hands.

If you are looking for an inexpensive, ambidextrous, light, portable mouse to use for power point presentations this might be the mouse for you but for the home user looking for an ergonomic alternative should keep researching.

All the variants of this device are the same China junk ! I had one of these, purchased at Wall-mart and I absolutely loved the design . It was the perfect hand-held mouse for me. Trouble began when the tiny components wore out . First the miniature ball-bearings wore out (flattened from not turning). Then the trigger (right click micro-switch) broke all within several months. I purchased another and , similarly , it broke down within a couple of months .
Recently discovered them (same product)on Amazon so I thought I would try another.
I was still desperate to have this trackball-finger mouse because I absolutely love the ergonomic design of the mouse and hoped it had improved . Sadly it arrived and this version did not function right from the start in fact; far worse than the Wall-mart versions!,
(the response of trackball to courser was between terrible and non-existent. I had some side to side response but no up and down with its trackball , I hoped this was just a bad unit, so I returned the item and seller promptly shipped a replacement, but sadly, it was the same -- again a similarly non functioning unit-- as the first . I have finally given up . I am very sad to admit : IT (this product) DOES NOT WORK. Badly manufactured. This is the perfect finger-mouse design, I really wished for , but unfortunately this product is a useless piece of junk and I finally have to give up on it . My warning : do not waste your time it Does Not Work! !
Ironically , I so wish to have a product of this design , but one that works .. so I would love to hear if somone ever manufactures one that functions correctly.

The first mouse I received came in four pieces, but was replaced within a week with a new one. It worked as expected for four weeks before the index finger button for the left mouse button froze. The construction is so flimsy that it will not last, I will look for something more durable.One Finger Trackball Mouse USB Type Black Color.

This trackball works by placing your middle finger through the hole in the bottom, the hole containing the trigger for the left mouse button. It does take some practice to click without going through a lot of hand contortions but not much. My hands are large but slender and I found this trackball useful for its advertised purpose: browsing. The left button on top turns on scrolling and works VERY well for that function. The trackball itself is not very sensitive so you have to run it a lot to move the arrow around the page. Use scrolling for larger moves and the trackball for smaller one.

I could not do two-handed typing while wearing this. You have to lay it aside. That said, it is easy to access the left click in the ring hole or put it back on. Again, you need to practice some. I have not tried this using my left hand; I am right-handed.

I use this trackball when I am surfing and do not have a surface for mousing (on the couch or outside) and do not want to use my laptop trackpad (which really sucks). It's small size is great for storage in my laptop bag and this beats using a small mouse which cause hand cramps for me.

I gave this 4 stars because it works as advertised. It will not work as well as a regular trackball (which I use a lot) but it fits into a mobile situation when a mouse and trackball just don't cut it.

What difference does it make if a product looks great but doesn't operate properly? This Chinese knock-off is pathetic in its inferior construction, and a failure as a functioning entity. Having worked with a different brand, I expected this to simply be a less expensive version of a great little mouse. I even bought two, expecting the price to rise. Instead of being a well-functioning mouse, it has turned out to be a rat.

On both mice, the thumb-ball slips, which causes the cursor to move severely erratically, and to add to the frustration, the ball ring which contains the thumb-ball is difficult to remove. The system is inertial instead of infra-red, which is always a bad decision for a trackball.

Did I return them? Nah. My time is more valuable.. and maybe that's just what the "HANDHELD" company - if that really is their name - is counting on.

I really do think Amazon.com needs to be more careful with their selection of vendors. This is my fourth experience with some type of poor vendors (NOT AMAZON, itself - they remain the gold-standard internet purchasing site). Oh well.. better luck next time.
