Happy vapiversary to me. I'm late to this thread, but must add my two cents.
When my first cigarette free birthday was upcoming (the date was the Saturday morning after Thanksgiving), I ordered two Vision Spinners from Myfreedomsmokes. For the previous year I'd been using genuine Joyetech Ego-T batteries, two at the office, two at home, which I believe will never die. They are my back-up batts now. I just got tired of them gradually weakening during use, giving me thinner, cooler vapor until the point when they flashed to be recharged. They've always been that way.
On my vapeday I opened one of my new Spinners. Using it with my new Aspire BDC clearomizer, I felt I'd reached a whole new level of vaping. When my Ego-T's were new, they worked for several days before requiring their first re-charge, so I was surprised to find my first Spinner flashing, as if wanting a recharge, after about 45 minutes of use. I put it on the recharger with wall adapter, the same one of several that came with my Joye Ego starter kits last year, but the light on the charger was green. So fine, I said, and left it charging but with a green light, and opened my other Spinner and started on it. 45 minutes later it wanted recharging too. The first one was still recharging but with the light still green on the charger, so I took it off. Flashing glitches can occur, after all. I put the second spinner on the charger, and the light on the charger stayed green for it too.
So I planned to contact MFS about DOA batteries, and went back to using the trusty old Ego-T's, grateful for their longevity.
Later in the day, I thought again about flashing glitches, and started vaping on one of the Spinners again. In about 45 minutes, it started flashing again, that visual scream for a recharge. I put it on the charger again, and this time the charger light was red. In about three hours it went green. I went to bed.
The next day I vaped on the fully recharged Spinner all day and all evening. While doing that, I put the second Spinner back on the charger, but the charger light remained green on that one. Hell, I said, but I went back to vaping on it. A few minutes later it flashed again, "recharge me!". I put this one back on the charger, and this time the charger light was red, and in due time my second Spinner took a full recharge.
The long and short of this: for my second vapiversary I'm getting Ego Twists! I have more respect than ever for the Joyetech name, and the Spinners obviously have some recharging issues, if I'm judging from this and a couple of other threads I've read since my experience.
