the cordless portion of this product set work fine most of the time although there have be a couple time I have to resynch it .  the keyboard be rather clicky and annoying if you have to listen to someone else typing on it . it feel okay if you be typing on it yourself .  I do not use the mouse anymore . I use a Logitech wireless trackball -lrb- which I love -rrb- . a nice thing be that I could the they trackball with the keyboard\/mouse receiver without add a second receiver .  the add control button be nice . I like the volume control wheel better than + \/ - button for volume .  I think I would like the left hand wheel but in reality , I almost never use it .  overall , its fine but I be not thrill with it . I probably would not buy it again but do not mind have it around .
