Ecosystem MK2

has anyone heard or used this ecosystem mk2 vertical growing chamber and if soo could u let me knoo what u think of it and if its worth buying

i was just looking at these in my local hydro shop. the dude there showed me a grow journal that his buddy made with this setup using the c99 strain. he said his buddy does 4-5 pounds in this every 56 days and from the pics i saw i believe it. this is shaping up to be my next build project....hope this helps
