Don’t waste your time of hard earned money.

but my arthritic thumb is having a hard time getting used to it!A

The first time I tried one of these I hated it...but it grew on

Having a couple early failures will not deter me this time, but I do expect a minimum of 2 years from a trackball

I was spending a lot of frustrating time with a mouse

I'm extremely disappointed in this product lasting such a short time.

(yes im guilty and learned from experience on previous models), you'll ruin it in short order, if you game although this is a great mouse for that you'll tend to be rough on buttons as well and the switches may get buggy on you if your rough with them, other than that if you have a light touch and use it regular-like it will last a loooong time ...... and #2 you do need to pull the ball and wipe out the socket every so often, maybe once a month .. battery life is good, no problems there ..

Like about 50+ times.

I also had some issues with the right pointer finger not always working the first time.

The ball doesn't work As accurately as I was hoping for It has a hard time focusing on small icons

Having a hard time using and my thumb cramps up.

My first time with a ball mouse, I love it, but this one is pretty cheap

Sometimes the mouse movement gets erratic, and I realise its time to clean it

i have dropped it many time from table to ground 3ft to carpet and working great

Comfortable, perfect response time, durable, and easily adjusted to for new people to trackballs (a friend tried it out and really liked it too)!

He has rather large hands and has a hard time finding a mouse that is comfortable in his and this one is perfect

laptop!It really minimized the pain in my right wrist caused by working on desktop / laptop all the time!

Doing more research on this producti discovered this is a very common problem and sounds like my trackballs actually lasted a pretty long time compared to others that lasted less than six months.

have no clicks or extra clicks at the wrong time and it can ruin your day.

Its been knocked off the couch by my dog several times, separating the blue ball, sending it flying, and it pops right back in and still works great.

Arrived on time & well packaged.

I started out as #19 in the queue, and at first the number went down fairly quickly, but as the number got smaller the time between reductions increased

Some people have a hard time adjusting to using their thumb to roll the ball but once you get used to it, it's so much easier than moving your hand around frantically all over your desk

so I would not recommend making the switch from a mouse to this during a stressful time.

Even a few months later I still tense weirdly trying to use the mouse like a regular one

so i clean i out regularly
