Liked most things about this kit, good quality tank and accessories mostly look well made. Docked it one star for the poor fixing kit. The bracket chewed into the red paint coating and chipped it. The screws are nearly impossible to access when the bracket is attached to the wall. The screws also chipped the red coating. Ended up putting a steel band around that is screwed to the wall to hold it all in place. Ignoring the fixing, this is still a good product and I'd still recommend at this price.
