Some of my drifting off the kanger path was the TFV4, very frustrating atty using the RBA with its random dumping of juice and constant dryhitting led me to shelve it before tossing it into a wall then considered it wasted money. It was when I discovered thinning of tails with rayon I revisited the TFV4 and its like a miracle was bestowed upon it. No leaking, dumping and hit after hit of great vape. Merlin was another atty so I could dwell into fatter multiwire builds but it seeped and seeped badly and I wasn't risking a expensive hitter getting fried by a cheap unthought out atty. It still sits and is considered wasted money. The couple jurassic drippers I have bought several years ago were just mess making units so never and still not really considering a dripper when I can build great cloudz in my STM and have no mess. Cartos and gennys were epic failures for me and gave all the equipment away so it can frustrate someone else.
I had mentioned that I like Kanger -- I think I feel comfortable with their products because that is what I started with. I now have the top tank nanos and their boxes put away and have been primarily using the toptank mini. For me, with the rba it works great - holds a decent amount of juice and does not leak. It's easy to use and dependable. I purchased the mini c which they billed as the successor to the subtank/toptank and I can't see why they billed it that way - small tank, the box is wattage only and no rba. it does have great flavor though.
I have two toptanks that I use daily -- one on the box that came with it and the other one on the mini-c box. Since I mainly use wattage both work fine.
I have been looking at other tanks and boxes and started with tanks first. I decided I wanted one that is either straight RTA or one that takes both coils and an rba piece. I purchased the TFV4 mini and I like it but I am constantly filling it so I cleaned it up and put back in stash. I did learn the thinning of the wicks as well and I had no leaking after I figured that out. I purchased a Geekvape 25mm rta that holds 6ml of juice and I really it - nice taste and no leaking. It's a little too big for the mini so I purchased a 3 battery istick 200 watt huge box on sale just to test out all the different tanks.
I've decided that I want to find an RTA or RBA that holds at least 6mm and is top or side filling. After I find something that I really like then I have received a few suggestions for a DNA75 box.
Then I should be good for a bit!
