put some ale into it last night primed 15 litres with about 40g ....bulging a bit today. no worries about the chassis of it but the cap / tap bit doesnt look the most robust...fired in some more hops too to offset the smell of plastic from it, as a precaution I have it sitting in an empty fermenter with the lid on....will try and polish it off at a bbq or the likes as i dont think it will keep fizz once opened.
