We offer a Happiness Guarantee on all orders directly from us on this website (we cannot guarentee this for orders placed on Amazon or through other vendors).
Happiness Guarantee: If you are not satisfied with your order, we will provide a returnless refund.
We typically ask if you are willing to try some troubleshooting techniques first. We want to avoid wasting a unit, if possible, and some repairs can be done in seconds (so you don't have to wait for shipping). If this does not work, we offer a replacement, parts to fix the unit you originally bought, and/or a refund. This may give you multiple units for the price of one. However, we will always refund you if you prefer over replacement.
