In addition to your statutory rights (listed on the website separately), the seller offers a 12 month warranty on all products used for private household use from the date of purchase (unless noted otherwise). The use of products for commercial purposes qualifies the purchaser to a 3 month warranty period.

Until the nature of any fault is determined, the resolution the seller can offer may vary. Where necessary, the item may need to be returned to determine fault/issue. If the products are unusable upon receiving or there is a major fault, the customer may choose between a full refund via the original payment method or a replacement product. There may be some situations that result in a reduced refund. In the case of a minor failure, the seller warranty may cover fitment of replacement parts or offer replacement parts to the customer. Other alternatives may be offered to the satisfaction of both parties.

Should you wish to claim a warranty on your item, please follow the process outlined in the Returns section.

Warranties do not apply where items are resold/rented for the purpose of profit.

You are entitled to recover reasonable postage or transportation costs if the product is confirmed to have a problem and is eligible for warranty, however, a receipt will be required.  Within 60 days of the customer purchasing the item, the seller may provide details allowing return of the item at no cost to the customer (where freight costs apply). If the product failure is found to not fall within the warranty provisions or statutory rights provided, you may be required to pay the transport and/or inspection costs (Estimates will be advised).

Prior to returning any item, our Customer Service Department must first issue you a Return Authorisation (RMA) number. All other relevant information will be sent to you at this time.

Returns are accepted in line with our warranty conditions.

Should you wish to return a faulty item, please contact us. Photos and/or videos of the item may also be requested to assist in the return process.

While many spare parts are stocked in Australia, we may need to order certain parts from the supplier on your behalf. Whilst most ordered parts arrive within 15 days, a small number of difficult to order parts may require up to 8 weeks to arrive.

    The product is very good as advertised,HOWEVER!!the Edison group let you down badly!they are hopeless offshore call centre refuse to listen and we're so bloody annoying I could never recommend this company so bloody hopeless! The main problem is their is no user manual or assembly instructions !with the laughable excuse of saving 50 million printed pages what a joke!i think it's against Australian consumer law not to provide safety and user instructions,they Edison's claim you just have to go on line and the manual is available after two hours of stuffing around the manual was not available!i had numerous argument with various Phillipines call centre folk who were unable to help ,claiming that although they represent Edison's they couldn't forward the instructions to me ,I must contact My Deal!after threatening consumer legal action remarkably they sent me the link immediately?go figure!so ANGRYbecause the instruction still didn't offer assembly instructions !very very ANGRYI like my deal and will shop again but never EDISONS again ever !chris markham
