Yes iv emailed lost vape over 30 times and they never reply, the vendor I got them from have offered a refund as they told me lost vape know about this problem and are bringing out a updated version but I’m holding on to them until the updated version comes out and then the vendor I got them from is going to swap them for me, bit shit that lost vape isn’t recalling all of these mods because the mechanism for holding the bottles in is absolutely rubbish, my bottles just fall out now as soon as you pick the mod up.
