It's not that people complain that it has too many WC options it's that for the price they are charging it has flaws that don't really justify the cost.
I am going full WC loop at the end of this year and the 900D has been on my wishlist since it launched as I love the design it's just the owners I've spoken to have said for the price it has too many flaws
These flaws are weak plastic on the mechanisms on the panels so when you pull in the switch sometimes that can snap the flimsy plastic tab underneath the panel which results in you having to awkwardly remove the panels through the bottom compartment.
The front I/O panel has a weak mechanism that is prone to snapping very easily.
for if/when we have issues. replacement parts galore avalible for the 900D
The front intake is practically closed off which realistically means not enough air coming in.
There are more and for the price this thing costs these should not exist.
