Thank You for your reply BrotherBob. So i guess this is something that happens with alot of RDA'S. The outer sleeve will rotate but the deck has to be loosened and tightened by hand. I am having a hard time with coils. I think i put the cart before the horse. I have a Wotofo Profile and currently use the mesh. The flavor is amazing but i want to try everything i can and i have a Peerless RDA just sitting here and be damned if i can figure out how to properly get the prebuilt coils inserted correctly. I have a ohm meter but it won't read anything when i put the Peerless in it. I've watched youtube vid's and they seem to fast forward through a lot of that part lol. Anyway i think i'm going to take it to a vape shop and see if i can maybe get some knowledge. I admit i got ahead of myself, but the peerless was on sale for 10 bucks. And i can't pass up a sale. Even if i have no friggen clue how to build lol. Just another quick note. I live in Canada and it's cold as a witches tit here right now, so i take a Smok RPM 40 to work, easy to sneak out and get a few hauls in, well anyway packing up yesterday and i was crawling around the back of the work truck because it has a top on it and it must have fallen out of my pocket. Of course it a long weekend. .......n it! I really like that vape. I hope it's in the truck and not buried in snow. Seriously thinking on getting the RPM80. I am also looking at the Smok Fetch. Just don't know enough about it so i will be checking out some reviews this weekend. Have a great weekend BrotherBob. Andy anyone else who reads this long winded post.
