It's no different than using Lendingtree. It's a company who sends your info to lenders who have paid to receive it as leads. You don't know if you're being linked with a bank because of their dependability and reputation, etc, but rather because they're the ones who paid this website the fees to participate.
You're best bet is to meet face-to-face with a loan officer who has been recommended to you by a past client of theirs or a Realtor, attorney, etc. meet with him/her and see who it is you're dealing with in person. Go over your loan options, fees and any questions you may have.
I'm always available to meet if you're still searching. Good luck!
