Highly recommending you, stay away from them. Have been trading with lot of brokers, haven't seen such execution nowhere of any order. Every one who is happy, don't count anything. With small spread, you actually trade with high spread forexample eurusd at least 1-1,5p + commission.
If you ar swing trader, then i cant tell you much, as those small 1-1,5 difference is not big deal. But scalping and day traders, no way.
