One thing the reviews don't mention about the Seidon 120V is that the mounting system is sh*tty. Medyo mababa yung mounting pressure due to the design. I suspect that this also applies to the Maelstrom 120K since pareho yung mounting method and hardware na gamit niyang dalawa.I can vouch for this. Weird kasi nung choice of material nila to provide pressure to the mounting screw. Plastic.. parang loose thread tuloy yung feel nung screw.
