Recommend me a doser

[DEL 707]

I'm looking to buy a doser. I'm currently dosing Reef Zlements InOne manually at the moment.

I don't have much room in my cabinet and absolutely no room outside of it. I need something I can screw to the side.

I've seen a Reef Factory Dosing Pump Pro X1, going half price on a website in my country.
Is it a good buy?

Im in the UK.
Shipping would be rather pricey.

My kamoer F1 Pro is about 6 years old now, it still works perfectly for me for dosing AFR.
