Extension tubes on Amazon.de

[Dmac60]

Looking tip my toe in the water of Macro and found these on amazon.de, anyone have any experience with these? Should I just play it safe and stick to Kenko? It looks like the ones on Amazon are Meike.

Edit: never mind, definitely looks like a Meike and ended up buying a Raynox 250 instead!

I had the Meike ones, they maintain AF and all cpu data, just like the Kenko ones. The Polaroid and Meike ones are about the same in terms of built quality. Pretty decent for the price.
