"Expensive for what it is.
Very difficult to determine if it does the job.
Let you know in 10years time!!
Other than price, all my rating are subjective.

"Just used this on a clean and flush for a customer. Hard to say much about the performance but at least the Fernox name offers some peace of mind for me and the customer.
And you get a little sticker for the boiler ;)"
