I am very satisfied with the solar water heater system which I purchased from EMS. From the very beginning, Mr Sookhoo, and the Sales Representative, Mr Goring, have been very reliable and demonstrated a often unheard of (in Dominica) attention to detail and customer service. The solar heater was installed in a very short period of time and the follow-up after purchase has been unexpected. So far. I have no complaints about the product or the pre and after-sales service. I commend EMS on job well done.
