I have used their service for more than 1 year. It is true that I have to open a bank in California to accept my money. But I am in Massachusetts. It is a big hassle to manage this separate bank account. Now I just received notice by mail there was a charge back happened in my account about 2 months ago. After checked with USPS, the product has been delivered to this customer with confirmation#. I called ECHO customer support and was told it is too late. I asked if there is anyway to get notice on time in the near future. She said you have to login your account everyday to check. They do not send out any email notice. It is user’s responsibility to track all these information. So stay away from this company if you can.

Their portal is seems to be developed in early 90's ? Very ugly and lack of many very important features (even basic ones like email warnings or confirmations).
I would suggest you to check another merchant processing company without requirements to go with their "First Something Bank" as only option for settling funds.
Also they advertise their ACH payment solutions as "NO Chargebacks - Guaranteed" - it's not true at all, we got chargebacks of REAL transactions from some scamming customer (we got his ID, Copy of the check and phone verification) - but Echo refuse to do anything.
So, I'm NOT impressed with their services at all - have to close account and move on.
