Dear fellow vapers I need some advise on getting another back up mod. I currently use one of the gotvapes vv rockets, I want another mod in case this one fails- I have not had any problems yet. I need something not really expensive, I use a really low ohm coil on my rba, I do not want something that will be throwing out alot of codee errors because of the low ohmage, my rocket does not fail to work with the lower ohm coils for some reason, I would like it to be preferrably made out of metal and have a good spring in the bottom of it,read out of ohm is not as important as it can go the distance, I do not want a box or anything that is not round, preferably a tube mod that as I said can be adjusted rather easily. Thanx for your help Ron R
