I don’t know if it’s a language issue but these guys don’t seem very keen to sell their stuff. One hasn’t actually made any attempt to answer my questions. The other priced themselves out of the market.
I haven’t bothered to look for more as until I sort out my Amazon issue I have no outlet for them anyway. But, as I found previously, once you start dealing with Chinese suppliers your spam ratio goes through the roof. I even have random Chinese numbers appearing on my Whatsapp now.
