So what's the consensus on these? Are they worth buying in order to keep the bottom of your saw in good condition or do they create other issues due to how it mounts? Does it act like a heat sink or damage the handle where it wraps around? I am interested in picking some of these up for my saws in hopes of keeping them in better shape, but I don't want to waste my money if they aren't worth it. What does this gang of misfits say?
