Very clean, easy to use. High cost.
This is very pure and clean to work with, but do note that by being lead-free had a much higher melting point that could lead you to damaging surrounding SMC. Be sure you had proper masking, and know what you are getting into.Proper ventilation and leaded solder is usually a much better choice for most non-professionals

It does the job half of the time
First it's very hard to get it using syringe. It's too hard, it just want get out. So, I need to apply two hands to get a bit of it. Second problem is that doesn't stick very well to the copper. So I need to use a toothpick to help it. The strugle doesn't end here, once it gets heated up with hot-air-gun it becomes too liquid and spreads way to much. Sometimes I have to resolder every thing since the paste goes underneth the components (SMDs) and short circuit. The problem feelt especialy on 0.5mm pitched SMDs. Sometimes it's handy but I would not recomend to a friend.
