Take my word for it...getting into the Pro Pointer and putting it back together ain't for anyone except for the experienced, and that means someone who had done it more than once. I broke mine once thinking I could help it by cleaning it out once, Garretts fixed it. I believe I could succesfuly do it right next time but it isn't worth the gamble to me. Besides, between the cost after converting pounds to dallars and shipping, PLUS THE INTRICATE DESOLDERING AND SOLDERING, this is a bear IMO, and I worked in electronicsfor 25 years. A soldering iron and solder won't cut it. Very easily molest the motherboard just getting a switch out. Garretts will be my choice pronto if I need a new switch. jm2c. martin
