Any reviews or info about Sunwing?

Hi! After seeing those cheap rates ($325 less then Westjet for our dates) I was wondering how reputable they are. I was a travel agent, but got out of the biz a few years ago before they surfaced and I havent heard anything about them. The post about their cheap rates on this board was the first I had heard anything. I know redseal owns them and redseal is a well known FIT tour operator.
Has anyone used Sunwing yet? Any feedback?
