No prob. It'll grant you a good chunk of the ex-1000's sig for considerably less if you can't afford the Ex-7550/800. Even after going thru a good number of TOTL phones, I still think the Ex-600 have got some real strengths that hold up
It's interesting that the H3 takes on a whole new level of performance with the vents patched up, almost feels like they've put square tires on a sports car :l
maybe closing vents work with h1 too??!!
