Puck locks are among the most secure padlocks on the market. This is because they often have a solid design without any exposure of weak points. Additionally, most such locks are made of heavy metals that are hard to break or melt.
Although many puck locks offer additional security compared to ordinary locks, some offer better protection than others. Top-quality products are better able to withstand picking and drilling attempts, so it might be better to invest in them than purchasing lower quality products.
