I have had a taxable account with Zecco for a year and a half and made over 300 trades in that period. Paid a total of $0 in commissions. No maintenance fees, no hidden fees-just 10 free trades each month (prior to January it was 30 free tades).
Moving $$ into and out of my account is easy with ACH to my local bank and is usually completed in a couple days.
$0 commissions has allowed me to persue a stategy of gradually scaling into positions by purchasing just a few shares at a time. I have been able to slowly build up positions in several ETFs and a number of blue chip financials (C, BAC, AXP, & TROW) that have been hammered of late.
The two times I have contacted them by email I got a response in several hours.
I don't know how they make $$ off people like me, I just hope they don't further reduce the free trades/month.
