I haven't had a chance to use the ballets spreader yet, but it seems to be well made. It doesn't feel cheap.
The rail cutting tool has proven very useful. Creating nice strait cuts providing you can hold it and the saw steady. I found found I get the best result using little effort letting the saw do the work.
Parell tool works really well on strait sections and curves.
The solder tool seems a little cheesy. Mine arrived with the rail grooves off center and a chip along one edge. The one groove was to close to the. Edge allowing to be damaged in the package. I have not had a chance to use the tool as I am using rail joiners to align the tails and soldering them in place.
