Oh Richie, you are so very kind and I appreciate your offer, but I seriously don't want these exact types again. I want to experience a different brand correctly. I do know Steve is sending me 2 tenergy unprotected ones, which is very kind of him, for me to see the difference. Granted, he knows I don't want to use unprotected, but I am going to try them just at least, as he requested so I can get 4-5 hours of vape. Mean while search for a protected quality one. Yes, it is truly frustrating because these the only ones I have ever had and I bought so many and I am unable to truly enjoy my Protege for hours like I should and my switch was NOT bad at all, it definitely is these batteries. I have appreciated Steve and Casey's help with all of this.
