all i can say is ive had a bad experience with their 33L tank
communication wasnt the friendliest, i drove over 3 hours to get this tank because i just loved these dimensions
when i picked it up the frame came RIGHT off, no adherence at all
there was silicon all over the place and to top it off the tank leaked on the bottom
it was only $50 i think and it wasnt even worth dealing with them
i know a LOT of people that has had bad experiences with them but i also know a few people who had good experiences with them but all i know is whenever anyone asks me about them i tell them to go elsewhere because of my experience
