It is the same device and it gets the same support and the same warranty from us, wherever you bought it.
The enclosure or the bundle can look different. Units supplied through schools, ClassWallet and resellers are sometimes packaged differently from the photographs on our webshop — a different case, or a different mix of accessories. That is a packaging difference, not a different product.
If an app does not recognise your device, send us a photo of the board with the casing off, along with your order or purchase-order number. Board revisions differ over time, and the photo is what lets us identify which one you have and tell you what it needs.
Support and warranty claims come to us. Email [email protected] with proof of purchase — an invoice, a purchase-order number, or whatever your school or reseller gave you. The warranty terms are the same ones in "Do your kits have a warranty?".
Returns and refunds go back to whoever sold it to you. We cannot refund a purchase we did not take payment for, so if you want to send something back, that goes through the school, ClassWallet or the reseller.
If you are not sure which of those applies, email us and describe how it was bought. We will point you the right way.
