Review on MOONWELL Pro Plumb String 26Ft by Doug Olson

I can't compare it to the Tajima brand as I don't have a Tajima to compare. But the Moonwell solder works well and stabilizes very quickly. The magnet sticks well to metal parts and the pen sticks well to wood. You can adjust the tension of the self-retracting line if you need to replace the bob with a heavier or lighter model; I didn't change the plumb bob myself, but I adjusted the tension to check. As mentioned, I don't have a Tajima to compare it to, but Moonwell appears to offer an $8-$10 feature versus a comparable Tajima.
