It is very important to us that our products perform exactly as described and that you are entirely satisfied with your purchase. We stand by all of our products to the degree that we will refund you in full if you are not entirely satisfied. Even if a particular product or service doesn't work for you and we refund your money in full, we will still go out of our away to help diagnose any underlying issue or fault, free of charge.
Please inform us of any damaged or defective items within 60 days of delivery and we will replace the item FOC or offer a full refund at our discretion. You may be required to return the damaged or defective item(s). This does not affect the manufacturer’s warranty where it applies.
Similarly, if an order is incorrect in anyway, please notify us within 60 days of purchase. We will endeavour to correct your order as soon as we can. You may be required to return incorrect order items.
If, for any other reason, you wish to return an item then please call us beforehand stating the reason within 60 days of receiving your order. Per our no-quibble money back guarantee, we will provide a refund in full for a single item if you are in any way dissatisfied, even if it has been used. Please note that refunds for opened/used products are limited to one item.
Any additional ordered items are still eligible for a refund but they must be returned unopened, in the original packaging and in the condition they were sent. A refund will be issued minus the original delivery charge.
Please call or email us for authorisation before returning any items. Refunds will only be credited to the same credit or debit card originally used to purchase the goods. Again, you will not be asked to jump through any hoops. We will process the refund and then help diagnose any underlying issue or fault, free of charge.
