Rated 2 out of 5Â by ramasaig2 Great idea, Disappointing
I thought this was a great idea. I fitted one a couple of years ago. Recently I came to change the radiator, and tried to drain it. I could not make it budge, and have now only succeeded in rounding off the square drive (using a brass radiator key).
Eventually I drained the radiator in the time honoured way by loosening the union connector.
Even after removing the valve I can't get the drain plug to move, despite 24 hour soak in WD40. There's no sign of corrosion, no lime-scale (this is a soft water area).

Rated 2 out of 5Â by Tode Needs non-standard key
Warning - the drain-off spigot size is 4.5 mm! A standard rad key (5 mm or 5.1 mm) is loose but will work when the valve is new.
I have one of these fitted. I needed to drain off about 5 years after installed, and found it jammed too tight for a standard key to open. A 4.5 mm clock key (available on line) fits perfectly - get a steel one if the valve is really jammed as it will break a brass key.
The new Pegler fitting I bought to replace the jammed one has the same size spigot, so they're still non-standard.

Of the 8 I have purchased the drain has rounded before it would open on 2 and the other 6 have all leaked, again through the drain off, to exchange for another product would involve altering all the pipework. Sorry, especially as they are relativly expensive, I can't recommend this product at all.

I too share a concern a previous reviewer had made regarding the limited small size of the bleed nut.
When I used my trusty brass bleed key, it slipped and could have easily rounded the nut off. Fortunately, I had an aluminium/nickel key in my toolbox which worked perfectly.
I wonder if something like: http://www.screwfix.com/p/plumbing-tools-by-rothenberger-4-way-radiator-services-cabinet-key/84379 may provide a better match of key
