Recently, I feel my device hasnt been performing properly on temp control. I'm using SS wire in one of those ego one clr rba's and i've always built the same way. But the last week or so it has taken me ages to get it to perform correctly. For example, I'm having constant problems with hot spots and hot legs on the coil, the coil not reading the resistance properly, and also a lot of the time I'll have the mod set at 500F and 60W and the device will only fire at maybe 5w resulting in no vapour. It takes me ages each time of messing around with various things to get it right. Like I said, i've not had these problems before, and I do everything the same. I've had the device since November last year and used it every day and I'm just wondering if a chip is beginning to go or something? I've kept the firmware up to date too.
