Rated 5 out of 5 by from Good value Bought as replacements for old units. Easy to fit and if the old ones were anything to go by, should last quite a few years.

Rated 5 out of 5 by from Easy swap over I purchased two of these as replacement for old TRVs that had broken, so quick and easy to swap over without having to change the whole valve. Great reduction in price as only the replacement head included and not wasting whole valve

Rated 5 out of 5 by from Great replacement 9 times out of 10 its not the actual valve that's the problem. Changing these over sorts the problem. I don't rate these actual valves myself, but if I come across a faulty one installed, changing this part fixes it.
