You probably can't find many user reviews because these guys don't offer market depth / level 2 quotes. No reasonable trader should be trading without market depth expecially when it's a availble from just about every pther broker with reasonable commisions. 

TC2000's charting is second to none. I prefer their charting and scanners over just about everyone. If they offered level 2 quotes and time of sales....they'll be very difficult to compete with especially with their trade diectly from chart features and adjustable stop losses / take profits by a simple drag. 

They're shooting themselves in the foot as far as brokerage clients are concerned but they're solid everywhere else.
