People rave about us:

Damian was recommended by a friend about 3 years ago. He is more expensive than my previous guy but at least twice as quick, so substantially better value. And Damian is always prompt with his service and good value for hardware. He knows what he is doing.

Was recommended by our Head Office to use Onsite TechSupport over a year ago and would not look back. They are very prompt and reliable with their service. I would recommend Damien and his team to other businesses and also friends for their home computers. Well done guys!

Sam Walton, Sam Professionals Modbury Real Estate.

Damien has been fantastic, installing a new computer and we are now wireless with 3 computers!, he is efficient and he speaks your language, not giving you too much info but just what you need to get the job done. I have no hesitation recommending his services to anyone.

Stacey George, Smartart

Great friendly service! Came out same day and got rid of the virus. PC runs like new again 🙂

Dianne Moule

We have had other companies come in to clean up our computer but it was only after Damain came out and in a few hours sorted out our computer and it has been running great now. Would recommend Damain to our friends for computer services required.
