>>You must specify that your clients use one UPS per PC. For our customers who does not have one UPS per PC, we charge about 200 USD per hour for the first time repair, 400 USD per hour the second time, 800 USD the tird time and so on. Sooner or later they get the idea!

For a 500VA UPS I pay less than 60 USD!!!
