Thats so funny! I had the exact same problems. Even with the 3rd one where the mic was screwed up. And the 4th laggs.... So I need another one, but Im afraid of a w600 lol. AND I dont want to wait on hold for 89 days..... lol Maybe Ill do it online.
i have the w600i. im not a big fan of it. i stiil use my s710.
i called lockline when my 3rd one was acting up and as always i had the person on the line assure me i was getting another s710a. 2 days later this different shape box shows up from ups and i open it and BOOM its a damn w600i 👿 . i called lockline steaming and they did nothing about it. so i had to buy anoter s710 outright. it was to bad i bought the 1st one outright and it was the last one any stores in my area had.
so i searched on ebay and found a cingy branded one for about $250.
a few weeks later i figured i'd hop back on ebay to buy an extra one as a back up and there were no more. 😡
the one i have now isnt bad but it does lag here and there.
