Hi. I am still having intermittent issues with my V2...when it works, it works great. But, and some of this may be my fault for poor technique, but it is very inconsistent. I will push the button 5 times rapidly to turn on and then wait and hold the button down to have it heat up, but it will not stay blue long enough...or even just stay blue, for it to heat up. I have recharged the batts over and over. Delta 9 sent me two extra batteries, but one has a torn covering and the other a rusty looking contact. The first battery, that came with kit, appears to look okay. Today I put the original battery in the charger. It first was red. Then after several hours, without touching battery or charger, the light kept blinking red. The I took battery out and re-inserted it in charger and then it went to green. But inside the V2 device, it is still is not working right...I just pressed the button down and it stay blue for just a couple seconds, not enough time to heat it up. I tried calling Delta 9, on both my land and cell phones, but the call will not go through...so maybe something wrong with their line. Any ideas?? Again, maybe I am doing something wrong. I have already sent it back to Delta 9 and they could find nothing wrong with it. I suspect it may be the charger or the batteries. Any ideas...and why cannot I not get a call through to Delta 9.
Thanks!
