They have a distribution contract with JEBO/Odyssea (a Chinese manufacturer) to sell in the US markets. The products are mostly junk, poorly made and my recommendation is to avoid them.
If you dare disassemble or study their products in any detail you will learn that they truly cut every corner in production and quality to get you those prices. Lots of cheap plastic, rough edges, and pieces that don't quite fit together.
However, if you are not demanding or picky about your hardware, and are just looking for a short-term fix, they have filters and lights that "work", and some on this board are happy with them.
IME with this company, you are really getting what you pay for. Low quality, shorter life products, but probably on target for the price.
