Unfortunately svboby makes great products but the shipper can be sloppy

received a stack of 4 2 inch rings. The 30mm has a small dent that prevents threading on the adapters. 10mm and 5mm are fused together and cannot be separated. If the shipper reads this I would like a complete and working stack replacement or a refund.

Pros

  • There are new competitors

svbony accessories are well made and have great prices.

I have bought several tubes, several extenders and focus reducers from svbony and they supply really good products at great prices. Only the roundness of the tubes is sometimes not perfect, which is noticeable when connecting or inserting with focusers or 1.25" holes.

Pros
  • Telescope Accessories
Cons
  • Crumpled

The threads are a bit short.

They appear to be quite well made and they certainly work, but the male and female threads are shorter than all my other M48 extension tubes and accessories which means the socket ends don't fully fit these other parts of the M48. So they actually offer a little more distance than the listed lengths of 10 mm, 15 mm and 30 mm would suggest. I suspect the difference is around 1mm. So if you only use 10mm tubing you can get an actual 11mm extension. Of course, the thread length matches the thread…

Pros
  • Photo Adapter
Cons
  • I'm writing back
