The supplier was very professional from start to finish with my specification. The customer representative contacted me and returned messages in good time. Despite the Chinese Holiday approaching, a quality control dispatch was arranged and sent by air freight which was with me exactly 7 days after leaving Hong Kong. Well done to the dispatch department because the 3 packages arrived intact. On checking the product it is of High Quality manufactured materials and the ease of installation is self explanatory via a YouTube link. I'm currently experimenting with the health benefit on myself to market the product based on personal experience before I consider purchasing further units for s business plan. Well done to ZOY!
