I'm using these to spike plain track on an On30 layout I'm building. I find them easy to drive and use.
As a suggestion for use though, the little plastic container (jar?) that they come in is tricky - for me - to open so I recommend placing that jar inside a larger container or tray before trying to open the package so if any spill, you've caught them.
