Query: Top part got stuck over time but it can be fixed

You'd hope the scent be a bit more present but it's very light but that's just how most vaporizers are (The outermost inside plastic ring) over time got warped and made it become EXTREMELY DIFFICULT to take the top off like a pain in the ass to take off bc there would be too much friction between the the top and bottom part bc of the warping. but I took a lighter to it and tried to warp it back it looks kinda bad underneath but but it fixed the problem of it getting stuck and you can't even see the warping from the outside when you're using it because it's all an internal thing so it doesn't really matter but I thought I'd share incase you start experiencing the same thing
