Review: I tried the rest then tried the best! - For many months I've had problems with air collecting in the bathroom radiator and tried auto air vents (Aladdin) without success. However, I fitted this product to the radiator yesterday and woke up this morning to a radiator as hot as all the others and no air present. It may be a tad more expensive then the other radiator vents available on the market but false economy if you go for the cheapest like I did and it doesn't work. This was well worth the money!
Review: Actually works - Have tried a few different types and this one actually works perfectly

- Automatic bleed valve with very compact, white painted brass housing and 1/2 inch male thread.
