Refund policy
Strict No Return & No Refund Policy
Due to the sensitive nature of electronic components, ICs, microcontrollers, and DIY modules — which can easily be damaged by static discharge, incorrect wiring, thermal overload, or reverse polarity — ALL SALES ARE FINAL.
Tecwizdom does not accept returns, offer product exchanges, or issue store credits or refunds under any circumstances once items have been processed or shipped. Please verify technical datasheets, operating voltages, and pinouts prior to purchase.
Cancellations & Order Modifications
All orders placed on Tecwizdom.com are considered final. Once an order is confirmed and entered into our fulfillment workflow, it cannot be cancelled, altered, or modified.
