33 minutes to explain a two minute job. Hmm.
As for benefits of the upgrade, the preheat function is useful (fiddly on older RX200 but easy on RX200S) but sadly is not a percentage increase but a fixed watts setting so be careful not to burn out a coil if you change coil and wattage. Ramp up on the S is so slow it's virtually nonexistent so it helps to activate the preheat and easy enough IF YOU REMEMBER to turn it off or adjust when changing to a setup that needs a lower power.
250W max and custom logo? Meh! Wish the screen layout could be changed instead. So damned ugly I have mine in stealth mode. Wismec should look at Smok screens.
