What else is there to say? It works. My parents told me 3 days before lockdown that they hadn't had any sound on their computer for 6 months. Turns out it was vital that this was fixed before lockdown. So i headed on down to pb tech. Went back the next day and "set it up" for them. Works a treat. Now my mum has to listen to the sound of my dad "gaming" all day while in lockdown.
