I have the sleeve on the evic VT and although I don't need to remove it to charge the battery, it fits a lot looser now than when I first got it. If I grip it lightly and hold the mod upside down, the mod will slide out of the silicone skin. Same thing with the silicone skin for the sigelei 75TC. And that one I was removing twice a day to swap out the batteries.They don't stretch or distort, certainly not the eleaf ones I have.
Even the VTC sleeve, which gets slid off at least every other day... is still perfect.
These should slip on like the i50, the pain in the .... would be ones like the D2 which slide on from the top and are more form fitted. I HATE having to swap that battery, but the sleeve is fine.
