I went ahead and picked it up and I'm glad I did it's a awesome mod for the price I paid. I updated the firmware and it's been running great it's very accurate in wattage and temp control according to djlsb. The battery door on mine is soild. I plan on getting the Sherman Rta so I have a tank that sits flush on it since it can handle up to a 28mm. I hope the mod last awhile.
