It does the job, but the magnetic part is like a square in the middle of the tube, and there's no way that won't be restricting the flow of water. Considering this is likely to be on the pipework leading up to an unvented cylinder etc, and if that has a balanced cold water feed, which it should, this could restrict the flow rate of the whole house. I don't see why they cant make them full flow like the 15mm ones normally are, i've seen other brands like this one too.
