I have been making and selling small items in Ebay for over ten years and in that time my products have been coppied but thankfuly my experience in a past life make my buyers confident so I still sell quite a few. Yesterday I notice a similar item to mine for sale and looking closely it looked like mine but with a fatal error in the construction, sure enough all the slating reviews it revieled the problem. Now last year I also made the error, quickly spotted it and sent replacements to all those who had the problematic item, Somehow this joker has no electronics knowledge and is still selling the faulty product HAHAHAHA
