Personally I have never heard about these brokers but I would say that every broker in the market is good if it's genuine. Some brokers can have slow withdrawal times but higher leverages. So we cannot say that a particular broker is not good. Maybe the requirements for everyone are different. I think testing out each broker would be a better method. When I was on the path of choosing the broker then I also traded with lots of brokers via demo and micro. I landed on Fxview and CMC markets which are good for me; so I think you can use the same approach for these brokers as well.
