I love my GLV. The only problem I've ever had with it is the threads strip if your not careful when you screw on your atty. I drip on an 801 so flooding happens fairly often and I have to take it off and blow it out. I've gone through two heads in the 6 months that I've had it, they're $30 to replace. I just chalk it up to another disposable part. I'm hoping someday that the GLV will redesign with a stronger metal for the threads (I've never had this happen with any other
mod) but for now I love my GLV more than my other
mods and I'll just deal with it. The vapor production, reliability and throat hit are second to none. By far the best
mod I own (I have six others) it's my every day vape. I only use the others for back up. Hope this helps.
