In most cases the first few results usually satisfy me. In this case, you may want to note the following:-
- Some mice are designed for use with notebooks only work within a meter
- Faulty mice are sold for parts but appear to be working at a quick glance
- High postage prices and no combined postage discount (One seller admitted he wouldn't cut postage because he would loose profit!)
- Some mice have nano receivers, while others have long pen size receivers. Know what you're buying
So don't skimp, buy a reasonably priced mouse and you might avoid these annoyances.
