My wife purchased the weller 12 watt rechargeable lithium ion battery soldering iron for christmas and I've only used it a couple times on car audio and the tip is pretty much junk and I was just gonna go buy a couple thinking they'd only be around 5 bucks or so and when I looked them up and saw the price of them I figured I'd contact the manufacturer and hoping they'd send me a new one or 2 since I just paid 60 dollars for this item and I don't feel like I should have to go out and spend 40 some dollars on a replacement tip after only using a couple of times. If you could get back to me asap since I have more soldering to do and I'm sitting here with a brand new soldering iron and can't even use it and if I have to go spend that kind of money for tips right away I'll just go buy another brand and I'll never buy Weller products again and I've always swore by your soldering products and I love the cordless iron but I believe the tip I got with it was defective because I know that they last a lot longer than that especially with someone like me that rarely does any soldering but when I do have the need to do it it's nice to have a product that works when you need it especially when brand new. I look forward to hearing back from you on what you can do to make this right with a loyal customer for years
