This is what appears to be the company’s first real review; the other reviews look fake and talk about how fast shipping was, which certainly was not the case in my order. Anyway, the product arrived safely and it was exactly as described. I’m very thankful because this was the only seller from whom I could find this product as a US consumer. Shipping took a few weeks which is completely understandable because it traveled from the entirely opposite side of the globe.
Positivo : Ho ricevuto quanto ordinato. Negativo : manca una qualsivoglia istruzione circa i collegamenti elettrici.
PTFE tubing as described. Took a while to arrive, but it came from other side of the world so not surprising! A+
