As an authorized addi dealer, all of the addi products we sell are backed by addi’s lifetime guarantee against manufacturing defects. If an addi item that was purchased from us proves to be defective, we will provide a replacement of the item at no cost. If an item arrives damaged, please contact us for immediate replacement.

We are not able to provide monetary refunds for defective items. If the identical item is no longer available, a reasonable substitute may be made at the agreement of the customer and Twitchy Hands.

We will send replacements according to our Shipping Policy via First Class Mail. For expedited packages, the customer may pay for upgraded shipping.

The lifetime guarantee does not cover wear and tear beyond normal usage, damage caused by accidents (e.g. pet damage), damage caused by unusual use (e.g. using tools in unexpected ways), or damage caused by improper storage (e.g. rust or bent needles).

If your defective item was purchased with another retailer, you will need to contact them directly for a replacement. If the original retailer is no longer available and you are within N. America, you can contact the addi distributor to fill out their replacement request.
