      This is good solder

      Overall: 4.5 out of 5

      I've tried several lead free "silver bearing" solders .. this is as good as any of them and priced much better than most. The melting point on this type is about 10 degrees lower than the non silver version. I recommend you give this a try.

      Remeber its lead free

      Overall: 3.5 out of 5

      I have used a couple of other lead free electronics solders (tin/antimony and tin/copper) and this is far better. If one were to compare it with a good leaded solder one probably would not be as enthusiastic, but if one needs or wants to avoid lead this stuff is pretty good. While silver is pertty darn expensive, 3% of 6oz is not really all that much and the price premium over the tin/copper version seems rather excessive. Still, while the price vs intrinsic value seems high, for the performance (again comparing this to other lead free) the price is maybe not so terrible. Note that 1mm is only moderatly small, one would probably not want to try surface mount with this stuff. even some of the finer through hole work might be a little akward.
