I am very satisfied with their service. My computer had a long 'Pain in neck' problem. It had intermittent fault of crashing for no reason almost from day one. I tried warranty from where I purchased also a couple of other service places to repair in vain with all sorts of data backing up and application, device reinstalling trouble.
I tried Netsquare recently as a last effort before I throw this monster out of the window. They magically repaired my PC with following details:
M/B BIOS updating, 750W PSU, Windows reconfiguring updating & tuning
Cost: $250+gst
My PC has worked perfectly since (more than a month now). I certainly will use them again!

Approximate cost: $275
