it was my first ever online buy, was kinda angry because of late in delivery (3+ weeks the Sony cam batt. and 4 weeks the Palm batt.) but seems Eastern Europe/RO mail system is slower. Had both products in hand just one day before vacations and this helped a lot.
About the product:
Palm Treo600: no more buzz, one charge last one week - more than with the original one when new. Sony FP90 cam - just made two weeks holliday with this additional batt. and no charger with me
