“Societies only have waste products while acquiring fresh raw material remains a cheaper option than recycling.” ― Peter F. Hamilton

About Us

We are a local tech start up based in Dorrington that was inspired by seeing the amount of things that are needlessly thrown away. It cannot have escaped your attention that we live in a throw away society, and I was well and truly part of that until one day...

WHY REPAIR?

At Mr Circuit we actually care that our customers are satisfied and that we are playing our part to protect the environment. We want to make repairing our electronics the default option and turn the tide against the throw away society.

  • REPAIR IS BETTER THAN RECYCLING

    Repair is sustainable, unlike extracting raw materials from the ground and using energy in manufacturing and shipping. Whilst recycling is better than throwing stuff away it still uses huge amounts of energy and is not as preferable as reusing things. By repairing our items and extending their lifespan we are being more responsible.

  • REPAIR SAVES YOU MONEY AND THE ENVIRONMENT

    Manufacturers want you to throw away your perfectly good stuff and buy new so they can take more of your money. We have the right to demand well engineered products that are built to last and not designed to fail. We also have the right to access technical documentation, schematics, error codes, and expect things are user servicable with a supply of reasonably priced spare parts.

  • REPAIR RECONNECTS US

    Repair can be learnt and problem solving is a useful life skill. Most people are put off from repair because they feel they lack the technical skills but in reality it is a logical process of elimination. It is actually a good thing to know how to repair things and one can derive alot of satisfaction from resurrecting a dead device.

PRICING PLAN

Here are some example scenarios of our pricing. We will always be upfront with you but this is only a rough guide as there are many factors that may affect our estimates such as distance, accessabiltiy etc. Please contact us for more information
