I still recall my first time experience. I bought the Fantasea housing for my wife go diving. First time diving ok, then few months later went for second time diving it leaked (flooding very fast and very badly). I wrote to Fantasea, with photos, they asked me to send money over to "exchange" for a new one, there is no explanation on why my housing leak or flood.
My wife has since told me, dun get a cheapo brand, get a "better quality" brand ones...
