I finally had the opportunity to use this to repair a microphone cable. Iron is thin and light. It heats up quickly. I tinned the tip using just one temperature setting (300), melted the old solder (the desoldering pump works great) and then soldered in the new wire. Liked the tip set. fans will love them. The tweezers are deadly and do their job perfectly. Not heavy duty and not sure how this product will hold up to 8 hours of daily use. I'm sure there are other kits made specifically for the trade but at a much higher price. But in this set everything is very functional. This is a good product at a great price. I'll be back with an update if this blows up in the next 3 months. :-)
