I bought and received a KUI Bottom Feeder. It is a true 1:1 copy of the Reosmod. First impressions: sturdy as a rock, works with all my 510 BF atties including all RM's, adjustable 510 connection, uses Reosmods parts (tubes, bottles etc.), only 2 colors available so far (silver and black), included atty is pretty good! Fire button is very sturdy with locking feature. Overall, I am very impressed! Just wanted to pass this info on! Available here: Kui bottom feeder mod | Scans Mod.
