Accuracy Guarantee
Elk ontwerp wordt gecontroleerd aan de hand van gepubliceerde bronnen. Vind je een natuurkundefout, dan passen we het ontwerp aan en sturen we je gratis een gecorrigeerde vervanging.
What counts
A factual physics error in the design, or in its printed equation or label, as sold. That means a wrong sign, a wrong constant, a wrong formula or a mislabelled law.
How
Email info@pixelatedphysics.com with your order number, a photo, and a description of the error. A photo is required. We verify it, fix the design and send a free corrected replacement of the same item. No return is needed. One replacement per item.
The 21-day limit does not apply to physics-error claims.
Print defects are handled under our standard print-defect policy, not this guarantee.
