I'm having a strange problem with my Reuleaux. I love the device, but, it hasn't been acting right. I think it has something to do with the battery tray and the batteries not making proper contact, but not sure. I went to Wismec website for support and only thing I saw was contact where you bought it from. For real? No way to get the thing back to them to get fixed or worked on? Not a good look on a pretty expensive mod. Anyways, here's what mine is doing...batteries are in the device. I vape on it and it works fine. I put it down and it shuts down to sleep or whatever and it won't come back up. Try taking batteries out and putting them back in. No good. Try batteries in different places in the tray. Nope no different. I said maybe the batteries are messed up or dead even though I know they are fully charged...nope won't come on. With the batteries in the device, I plug either car charger or wall charger into device and bam! Screen starts to boot and I can plug it out and vape on it. Battery level shows batteries charged. I use it all I want as long as it doesn't sit and go into sleep. The only way I get it to work again is same thing. Plug it up to get it going then it's good as regular. Anyone have this happen or know how I can get Wismec to fix it or do something about it. I really do love it. Just want it working right. Thanks all!
