"Sturdy brass rather than zinc key so is much tougher, no more broken zinc keys with twisted off handles! Good value for money as its built to last and is comfortable to use. Unless you have the fingers of an infant like TH3PLUB3R must have, in which case you could just turn it with a small wrench once located on the valve."
"I have actually had keys like this not fit before, this one does fit. Hurts your fingers a little if the bleed has been over- tightened but this should avoid the bleed from being over-tightened in the future. Can't see that it would ever fail but i generally lose them so it would be nice if there was some way that this could be attached to a key ring or lanyard of some sort."
"Bought this with high hope after reading all the reviews.
The key is useless - it is very small and the 'handles' are tiny making it is impossible to hold and turn the valve on the radiator. I tried to use it on my radiator but could not get any purchase to turn the key; so had to endure a cold bathroom while waiting for an order for a key to be delivered.
I suggest you save your money and buy something bigger which will do the job and do it easily."
