High Power, Critical Support Failures.

User Reviews

Reviews on Trustpilot are overwhelmingly negative, resulting in a disastrous 1.4-star average among 45 reviewers. Users report severe problems related to aggressive licensing enforcement and non-existent customer support 😬.

Multiple merchants detailed receiving automatic DMCA notices from Out of the Sandbox, which unilaterally resulted in Shopify shutting down their entire stores, sometimes for multiple days, and causing significant lost revenue. This practice occurs even when the theme was legitimately purchased, often citing issues with registration or ownership transfer.

Recurring sentiment indicates that customer support is unresponsive and consistently unhelpful, frequently taking weeks to address critical issues or redirecting verified users to hire expensive third-party developers, even for fundamental bugs like lazy loading on hero images causing CLS issues. Current and previous customers strongly warn against using the theme due to the high liability risk associated with the company’s business practices and catastrophic support decline, suggesting the core value of the powerful theme is entirely undermined.

What users say elsewhere

Prabir B.
Trustpilot

Imagine them DMCAing their own customers, leading to Shopify shutting down the entire site. If you use one of their themes, recognize it's a critical liability now. Stay far away and don't look back.

Charles H.
Trustpilot

Support has sunk to an atrocious level. Every ticket is met with 'contact a 3rd party developer,' even for definite, reproducible bugs in the Flex theme. They refuse to support their expensive $500 product.

Richard J.
Trustpilot

I received a DMCA notice for a theme bought by the previous owner of my business. Now they demand proof of the original order or I must pay $500 again. Don't even mess with these guys.

Chantelle F.
Trustpilot

They issued a DMCA notice and gave me less than three hours notice. They kept the store down for four days, causing major lost revenue for my small business. This company is totally unethical.
