Highly recommended!

After testing many similar plugins, this one stands out as the most powerful. It allows you to set min, max, and step quantities not only globally or per product but also for individual variations — and all that is available in the free version! It even supports decimal quantities, fixed quantity options, and dropdowns for easier selection. Support is excellent — quick to respond and fix bugs. The only downside is that the interface can feel overwhelming due to the abundance of features. A bit more simplicity would make it perfect. Highly recommended!
