v1 on the cheap? Ignore this whole thing if not.

It was never my favorite with the stock coils (0.15s), and always felt too airy with muted flavor for me. The "take to work" vape is the top
tank mini with stock coils (0.15s). But... I did enjoy the original crown using the rba head. So if you build, it can bump the flavor up. I just don't take rebuildables/rtas to work, but that's probably just me.
Crown never leaked on me. Easy to take apart and clean and such. Low maintenance. Threads were never stellar, but never caused an issue. Solid, and depending on your usage might be great. Sadly it depends.
