Successfully trading with zecco.com now

I've successfully placed my first few trades with zecco. I am starting out VERY small to test the system, but so far, so good. Bought 2 shares of Microsoft (placed the order around 7:00 a.m., it was executed at market open of 9:30). The price dropped later in the day, so I purchased another share to DCA my cost down. That order was filled almost instantaneously.

However, I do have another poster who was complaining about zecco, but with no real details. I'd be interested to hear more of their problems, so we can hopefully avoid them in the future.
