Antex had a load of problems with the tcs 50 irons (Chinese made) Luckily they honour their guarantee and send replacements. I had 2 go south one straight from the box but the latest batch of replacements have worked fine so far, and when working they work great. Although if one conks out again i'll bite the bullet and get one of these https://www.conrad.com/ce/en/product...450-C?ref=list The Ersa tips virtually last forever. I'd be curious to know what the coating is on their bits that stops them pitting.
