Our Verdict
King Checkout Validation appears to be the stronger choice due to its high rating and positive reviews, suggesting better performance and user satisfaction. Its granular customization options using regular expressions and focus on compliance make it ideal for merchants who need strict validation of customer data, especially those dealing with international customers or regulated industries. Blockit, while offering broad validation rules, lacks reviews and a clear demonstration of its effectiveness. Without user feedback, it's difficult to assess its reliability, making it a riskier choice unless the merchant specifically requires only its broad features.
Common Questions
Which app is easier to set up?
Based on the descriptions, Blockit might seem simpler due to its focus on broader rules. However, King Checkout Validation's well-defined features and positive reviews may indicate a smoother overall experience despite its complexity. Without user reviews regarding setup for Blockit, this is speculative.
Which app is better for preventing fake orders?
Both apps aim to prevent fake orders. However, King Checkout Validation's detailed validation, including the ability to block non-Latin characters and validate VAT/Tax IDs, might be more effective at detecting and blocking sophisticated fake orders.
Which app offers more customization options?
King Checkout Validation explicitly offers more customization through features like regular expression validation and validation rules based on order amount, weight, and product type. Blockit focuses on rules based on customer, order, cart, and shipping details but lacks the same level of granularity.

King Checkout Validation, with its ability to validate VAT/Tax IDs and block non-Latin characters, appears more suitable for international stores dealing with diverse customer data and compliance requirements.
