I was able to find a very reliable and helpful supplier through Alibaba. There may be some less-than-helpful suppliers out there, but through proper research and communication this site can give an endless array of opportunities to find excellent manufacturers to do business with! I don't typically write reviews online, but I think it's worth it given that this is something that has made a big impact on my life and does a great service to the world by getting buyers in touch with suppliers in such an efficient manner.
