Looks like my first review on this product. This item deserves a review. When I ordered the price was $26 (now it's $48). This item and the box it came in are marked Meike. I believe the "A" at the end of the model name indicates a metal mounting ring. The same models with the letter "B" at the end have plastic mounting rings. This seems to be the same for different lens mounts (Nikon, Canon, etc.). For the price the quality seems quite good. The case is made of plastic. The mounting ring appears to be metal, but it is very light and non-magnetic. Everything fits well, doesn't sag, doesn't constrict. The contacts work, I tried the stack with Oly 45mm 1.8. I could change aperture and focus. These tubes seem like a good choice for the M43 in this price range. Highly recommended. I will update the rating if/when warranted.
