Review: So well made! And does all my radiators! - Such a handy little tool! I previously had a small brass key. But it was so small and fiddly, that it took a few attempts to get it to latch in place! My radiators are a plumbers nightmare! I must have a small hole in my pipes, as two of the radiators fill up with air. The top halves do not heat up when there is air in them, meaning that they are inefficient. So I have to bleed them every two weeks. Oh, and a few years ago, I had a new radiator installed in my lounge. And up until ordering this key, I didn't even know it needed a different type of key! I just thought I was being silly in not finding the bleeding point! I misplaced the little brass key, so came on here to buy another. And I VERY almost bought an identical one, at half the price of this one! But then I read the reviews, and a lot of people said the same. That the grip was rubbish, or the key snapped. So I carried on looking and found this one. Yes, it was more money. But I'm glad I paid the extra, because it was worth it! It came well packaged, in a little handy zip bag. It's also incredibly well made, very sturdy and out of strong materials. I like the size, as it was so much easier to use! The long handle made it a doddle! And as mentioned earlier, I now know how to bleed the newer radiator! I know there is no way this key will snap! It's too strong! So yes, although you can buy cheaper keys, this one is better in the long run! And it's so much easier to use! So this is definitely a 5 star gadget! Will be recommending this one if anyone I know needs one
