I have the Mod version of the G43 and love it as is. It is definitely a heavy hitter with some of the best vapor around. I purchased the parts kit from VG and the power supply that Bud recommended and it makes the G43 even better. I'm pretty handy (some arthritis in my hands) so putting the connectors on was a bit of a challenge for me but doable and WELL WORTH THE TROUBLE! Once you dial it in you can just leave it on and hit it for cloud after cloud without any worry about battery life. Last thing is the incredible service that VG has, always fast and friendly service and happy to answer any questions you may have. Highly Recommend!
