Hayward CX1200RE Cartridge from Amazon

[apono]

Sold and shipped by Amazon. Is it fake? To me it's 100% not original. Doesn't add any pressure even while cleaning algae.

I contacted Amazon and they sent a replacement - absolutely the same cartridge. I sent a message to Hayward support, let's see what they think.

What filter and where to buy to avoid fakes?
