I use this to fix my Macbook Pro Logic Board and it seems to be doing the job quite well. That's a bit more than I need, but that's my fault. I would buy again.
The product I received was not as advertised. When I received it it was 3mm wide. The seller said he would give me a 50% refund. I needed this for specialized work with fine pitch surface mount devices. I will no longer buy from this seller.
