/vape/ - Vape

i started vaping about two months ago. started using a shitty vapage battery and cheap plastic tank i bought at a local tobacco outlet, and used green leaf ejuice. about a week ago after starting new job, i ordered an mvp 2.0 online along with a dozen or so bottles of mvp juice, and a protank 2 with a 5 pack of coils. my problem however, is that i think i probably broke my protank trying to twist it off after getting stuck. i swear almost every time i went to twist the tank off to clean or refill it, either the base would get stuck to the battery or the bottom metal piece would get stuck to the base. i had to use a fucking pair of pliers every time to get it off. a few days ago while twisting the protank off with pliers, i heard and felt a pop/crack, after the tank came off, i looked and this metal ring piece that used to be attached to the bottom is now loose, you can see it in the lower left hand of the pic and in the second pic as well. does this sit back on somehow or did i break it off?
been using the iclear that came with the mvp but am getting burning taste more often and not as good taste and clouds as i got with my protank.

what can you guys recommend for a good glass, bottom coil tank thats relatively easy to take apart and fill, good with preventing leaks, and most importantly one that i wont have to fucking pry off with a pair of pliers every time?

also, the order on mbv kinda fucked me over because it was like they waited a few days to charge my debit card which made me think i had way more money in my account than i did which left me greatly in the hole with an overdraft fee, i dont think im gonna be using mbv for anymore vape purchases. what is everybody's go-to site for buying vapes/accessories/juices?
