We don't recommend combining 2 or 3 rings at the same time if the focal length is less than 70mm. the autofocus is easy when mounting ONE ring, but difficult for 2 or 3. We suggest setting your camera in MF.
Please see 5th image, that's my testing data, hope that's helpful for your photograph, if you still have any problems using it, please feel free to contact me, I will provide technical support, Thanks

As for something of this price point, this indeed is a great option. It came well packaged and with appropriated instructions. The tubes worked fine with my Canon EF 50mm f/1.4, although a bit slower than normal in AF mode. Only downside is that the delivery time took quite some time to arrive, they should better inform that the piece comes from China and not from a warehouse in EU.
Not bad it works well, even they are made in plastic
Works fine. Still have to take some good pictures!
Nice firm fit , not loose like some cheaper brands
