I've banked with Wells for well over 10 years including checking, savings and a home mortgage. I left a small credit union that was on shaky ground financially and, at first, was hesitant to use a large bank. I have never been unhappy with the service I've received at Wells. By having the mortgage with them and keeping a reasonable minimum balance I get all my banking for free. Wells has great online banking options and a very good mobile app. I also love that there is a branch on every corner in Las Vegas.
Over the years I've had little glitches with them here and there, but they fixed the problems quickly and without hassle. There is not perfect bank (or any other business) but I think Wells does a great job at keeping customers happy.
