Hi Bovinia, After 3 button replacements on my wife's IPRO my beloved Buzz Pro's button caved into the body, the button was alway's shorter than my wife's IPRO. My question is how much does it cost to replaced the button on my Buzz? Also have they hopefully improved on these buttons? I already have a RMA printed out...But if it cost to much to fix I might retire my buzz and look elsewhere as the buttons don't last long. IMHO the buttons are prone to break.
