I massively prefer the Geekvape one. I did manage to find a very similar alternative. I'll post a link when I'm home, I'm sure I saved it as a favourite on my laptop
True. Stentoiran is (I have one, black) too flimsy. The heavy steel top makes it standing very unstable and I do not like the idea of having it in the pocked where the silicone part is unprotected against the shocks/pressure. TO make full comparison:
Element-------------------------------------GeekVape Flask-----------------------------------------------------------Stentorian bottle
Shell------------------------------------------Full, enabling easy liquid push via side opening--------------Upper part only
Needle tip----------------------------------Metal--------------------------------------------------------------------------Plastic
Squonk tip seal---------------------------Elastic-------------------------------------------------------------------------Rigid
Cap seal-------------------------------------Elastic saddle in the cap------------------------------------------------Oring
Bottle seal/cap----------------------------Flat surface, polished----------------------------------------------------Serrated, may damage the silicon bottle surface if
-------------------------------------------------------------------------------------------------------------------------------------overtightened
Therefore, while I DO have Stentorian - I was searching for the Flask constantly.
