I got in a while back, transferred some money in, then realized that it's no better than my credit union (actually worse, in it's current stage) feature-wise (yet, hopefully), and transferred my money back.
Once they add check deposit by picture, they'll be beating my particular CU in one key area, but I think I'll still keep my spending money with my CU for the time being - it's much easier to have my banking needs taken care of in one place, and my credit union hasn't scammed me, misplaced my money, or charged me an unreasonable fee yet (and I don't expect them to start).
