I'm thinking of buying the sigelei 100W Plus Box anyone got one 
I have the regular 100w (not plus)
it's been put through a lot of use a one significant drop (not my fault) and it's still kicking with no issues
hi, i have a minor problem with my sigelei 100wplus, my voltage is jumping with an increment of .1 is this normal? for example i have a .2ohm build and at 72w its reading out at 4.2v. sometimes when i fire the mod it reads out 4.3 and then back to 4.2 after firing it again the second time. it just jumps to 4.3 and 4.2 everytime i fire the device. this happens with all of my atomizers with different coil builds. hope to hear from you guys. thanks!
thank you so much mate for your reply! anyway im using nichrome wire, you think changing to kanthal wires can solve this?This is because of small variances in the coil's resistance, and the mod is doing what it's supposed to (providing you with your set wattage). If the voltage were jumping excessively (like from 4V to 6V) it'd be problematic, and would likely mean a short in your coil. As it is, nothing to be concerned about.

ok mate. kudos to you! thanks a lot! now i can have good night sleepsEhhh not necessarily. Coil variances are just a natural thing, part of it is the accuracy of the ohm reader built into the device. As gunk builds up on the coil, the resistance usually rises a tiny bit (like .05), and that can set the resistance to a tiny difference. Since the device isn't reading all the way out to the hundredths/thousandths, it adjusts for a sort of "rounded" resistance.
