I have a Hellboy - been modified for bottom fed.
I rather like it.
It is very airy , even for me who likes some air Im using it with two holes open each side.
Currently have a 26g nichrome 2.5mm 5.5wraps 0.32Ω build in it.
First version came with its own non changeable drip tip set up , second versions came with a drip tip adaptor.
I got the first version but have had no issues with the stock drip tip. Its metal and some might find it too wide at the top but it tapers down smaller to the part that my lips go around.
Does come with phillips screws which have been ok for me but in the past I have stripped some of those screws on other attys , so use a screwdriver that fits them good.
