Pick the right address and you'll get a faster answer: each one goes to the person who handles it.

Help us answer faster

Whatever you're writing about, these three things save a round of emails:

• Your order number: it starts with # and is on your confirmation email.
• The kit name: as it appears on the product page or the box.
• A photo, if anything is damaged, missing or not behaving. A phone photo is fine, and it usually replaces a paragraph of description.

You might not need us

Three questions come up more than all the others, and they're already answered:

• Delivery times and costs: see our FAQ.
• A missing or broken part: the full process is on our replacement parts page.
• Lights that won't come on, or a gear that binds: our troubleshooting guide walks through the usual causes in order. Most builds are fixed at the table in five minutes.
