Repaired, not Replaced!

We are committed to reducing e-waste in Australia. How we do it is by educating our customers on the reparability and longevity of their devices, as well as providing affordable Macbook Repairs here in Adelaide.
Although our best intentions and hard work, this is not an easy task. Customers must accept that cost of high-quality electronic repairs, is between a third and half of the price of a new device. However, with the current trend of planned obsolescence in electronic design, we see more and more Macbooks having shorter lifespans. To tackle that, while we do our repairs we target common planned obsolescence engineering design mistakes to ensure we extend the life expectancy of the Macbooks we repair. Check some of our Macbook Repair Cases to get an idea of the process.

That said, if we buy a new one or write it off via insurance, it does not guarantee that the new one will not meet the same fate as the older one pretty soon.
As matter of fact, quite often we see accidents reoccurring within less than 2-year gaps. If we can save 2000$ or even 1000$ today by repairing our faulty Macbook is brilliant. That’s an extra half Macbook cost ready to be spent on another one when the time comes or our need for performance increases.
When that time comes is up to us to buy a new one or keep pushing the one we have, but delaying it by a year or three is always a good starting point and saves another abandoned Macbook from polluting our one and only Planet.
