Im so sorry to hear that, In '98 my best friend went to the doctor and passed 11 days later. I feel you on that. Its like they are ripped from you before you can even process the bad news.
Kind of the same for me. I had just bought Two eGo V V2's and I was using a Kanger Protank 1 and 2. Then I thought I'd get A Grand Vapor Trident and the battery instantly got warm so I stopped Immediately and ran up to the local vape store and walked out with a provari. I sold (2) eGo V V2's and (3) eGo C's, (4) Clearomisers and (8) atomizers for them. (2) Chargers and recouped some of my money but you never get it all back. I'm of the thought, if you're going to go, go BIG!!! I just got my new end cap and 18650's yesterday. Now I'm blowing clouds. The noise isn't very loud and the button seems strong, my OCD was kicking in so I thought I'd ask the "vets" if the sound was was normal. It's very slight. The button isn't loose or moving freely, I just noticed it when I kinda Slid my finger across the the button. It's more the sides of the button touching the sides of the opening of the hole. It doesn't move in or out freely just side by side. Ya know? Anyway I'll stop rambling. Thanks for the help.
