So I need new climbing rings for my Maytronic M400, the original part is very expensive. Do you buy genuine or some other cheap alternatives that's possible to find online?
To the OP, looks like the rings on Amazon.se are about $20 USD, or $220Kr. That is about as good as it gets. I have used both aftermarket and OEM in the past. I liked the OEM, but I had both good and bad with the aftermarket (one set was fine the other struggled). Hope that helps!
