Well I got my kit today. It only took about 2 1/2 hour to build. Works great!!! But I had only one issue the board gets alittle warm after a few hits. I guess that normal. Oh and I made 1 big no no. I hit a ec2 tank I made with 6v. Man It looked like it was going to melt. Lol. One suggestion I have, to who ever wants to get one. Get the voltage meter too. It's well worth the 15 bucks. Just wished there was a way to have it built in the mod box. But for the price of the meter and the box and a few hours building the mod you feel like you've created a monster vaping machine. Thank mad vapes. Oh I got 2 14500 batteries and a charger on amazon for 14.00 counting shipping. Thanks again
