I know a thing or two about tips and they're the best in town. Hakko is known for giving really good, hot advice, and they definitely didn't "get caught" with it. Now, I know most people say you have to be careful where you tip, but I use mine almost everywhere. I've rubbed the tips all over the house just to see how it feels! I was also told to wait for my tip to warm up a bit before starting rubbing it all over my body, but with that I found I was rubbing the tip as it got warm! Let me tell you it's great! I had to do some work on my Lenovo T480, and heck, you know, I rubbed my new attachments in there. I mean I was actually able to get there. 11/10 would recommend these tips to everyone I know. I've already recommended her to a few ladies and before you know it I've got every girl in town wanting to double check my advice! Very good product.
