Query: Absolutely Not Recommended

From my own experience, I must say that the Trackball is not a good buy.1) The price is a bit steep for a mouse. Yes, it's most likely due to the fact that it's a track ball mouse.2) The whole thing seems very unprecise. I once tried clicking the minimize button and I closed the program window instead! Luckily, I was just viewing something on the internet but if it was a document you risk the chance of losing it.3) The mouse is simple too bulky. The buttons on the mouse need to be configered, for example you cannot simply double click on the first action button, you have to infact select a mouse button and assign a double click function to it. You also have to assign a right click button extra, leaving you with few buttons you can configurate yourself.Ultimately, I would urge buyers to shy away from the product. It simply is not worth the price. Yes, it does look sleek and stylish, but it's just not worth the extra bucks and sacrificing functionality for aesthetic appeal.
