AI Overview
Performance snapshot
Knowband is a niche eCommerce module and mobile app builder vendor, primarily serving PrestaShop, OpenCart, and Magento store owners. Across 119 reviews spanning multiple platforms, the evidence is sharply polarized: a strong cohort of satisfied clients praises fast, responsive support and affordable pricing, while a substantial volume of negative reviews cites non-functional modules, refusal to issue refunds, and a pattern of upselling to resolve issues that arguably should be covered under warranty. Recurring complaints about billing for bug fixes, compatibility misrepresentation, and unresponsive custom development teams create a Mixed-to-Weak reliability profile that materially undermines the otherwise positive support narrative.
Performance breakdown
Technical expertise
MixedSeveral reviewers confirm working modules for Google Shopping, eBay integration, mobile app building, and checkout optimization across Magento, PrestaShop, and OpenCart. However, a significant volume of reviews report PHP errors, API incompatibilities, and code quality described by an independent developer as 'very bad,' indicating inconsistent technical standards.
Project management & delivery
WeakMultiple clients report that custom development projects were not delivered despite upfront payment, with one specific case citing five months elapsed and no deliverable. Timelines appear unreliable for custom work, and version updates have reportedly erased previously paid-for customizations, reflecting poor delivery governance.
Communication & collaboration
MixedMany reviewers highlight fast, responsive support for standard module issues, with resolutions often achieved within 24 hours. Conversely, multiple clients report tickets closed without response, ignored messages during custom development, and communication that abruptly deteriorates once payment is secured.
Reliability
WeakA persistent pattern of modules not functioning as advertised at launch, recurring bugs after patches, and security vulnerabilities reported in production environments undermines confidence. Clients across multiple years and geographies report identical failure modes, suggesting systemic rather than isolated quality control issues.
Client satisfaction & outcomes
MixedSatisfied clients report genuine business outcomes including restored Google Shopping feeds within 24 hours, mobile apps live on both iOS and Android, and 3,000 app installs over three years. However, a comparable segment reports financial loss, business disruption, and no remediation, making aggregate outcome delivery inconsistent.

The review base is large and recent, with the majority of reviews published within the last three years, providing a current and statistically meaningful signal. The single Clutch review, dated May 2023, is negative and low-density. Review date range: 2018-04-10 - 2026-08-27.
