The REES52 Promise

We want you to build, not worry. Here is exactly what happens if something goes wrong with your order.

Dead on arrival or defective? We replace it.

If your item is dead on arrival or has a manufacturing defect, tell us within 7 days of delivery. Email support@rees52.com with your order number and a short video or a couple of photos showing the problem. Our team will get back to you within 24 hours and arrange a free pickup from your doorstep - you never pay return shipping for a defective item. Once we verify the issue, your replacement ships out right away. If the item is out of stock, you get a full refund instead.

Refunds, with real timelines.

  • Approved refunds go back to your original payment method within 6-7 working days.
  • Missing item in your package? Tell us within 7 days with photos of what arrived and the parcel label. Once confirmed, the refund for the missing item reaches you in 2-3 working days - or we ship the missing piece free, your choice.
  • Every refund comes with a reference number by email or WhatsApp, so you can track it with your bank instead of chasing us.

Wrong item or not as described?

Email us your order number and a photo of what you received. We arrange the return pickup, and ship the correct item as soon as the return is on its way. Prefer your money back instead? That is fine too - full refund, same 6-7 working day timeline.

About lead times on some products.

A few items on rees52.com are sourced from our overseas partner warehouses and are not sitting on our shelf. Those products show a lead time of about 20-25 working days on the product page, before you pay. If you order one, we keep you posted as it moves. Changed your mind while waiting? You can cancel any time before dispatch and get a full refund within 6-7 working days. No cancellation fee, no questions.
