I traded with SiamOption last year, and I would say that the trading environment and platform are both very user-friendly. The customer service was also quite enthusiastic and responsive. However, there were some hiccups during the withdrawal process that caused some inconvenience, but the issues were resolved quickly. I would still give this broker five stars based on its over performance.

Terrible trading experience with this broker. I can no longer place any trades with my live account or withdraw funds without getting an error message. I called live customer service which was useless anyways only to hear that my account was blocked.
