Our Verdict
For merchants prioritizing a better shopping experience, increased average order value, and visual appeal for quantity selection, Extendons Quantity Selector is the superior choice. Its focus on customizable buttons and real-time validation can lead to a smoother customer journey. However, if the primary concern is preventing over-ordering and needing highly granular control over inventory limits, even down to individual customer levels, then UpsellFly:Order Limit Quantity might be a better fit, despite its significantly lower ratings and fewer reviews. Merchants should carefully weigh the importance of user experience against the need for strict inventory control.
