Absolutely Free. Period.
Bring a device to Techmate, drop it off and we'll look at it for nothing. No deposit. No cost. No hard sale. Have us diagnose it, get it fixed somewhere else. We have no issue with that.
Other shops charge for diagnostic, or they say "Free", but charge a "Deposit" which you will never see again, Techmate is changing the way computer repair shops do business. No charge, no deposit, no hassles.
