After having problems with my Z2 I contacted garrettoomey about doing an upgrade to a Z3. Garret ansewered all my questions I had about my hdd and responded to all my emails. I overnighted my hdd to garret, he recieved it, upgraded my exsisting hdd and finished it that day and overnighted to me. Once I recieved my hdd I took maybe 5 mins to install and everything worked perfect.
I would highly recommend garretoomey, for his fast and honest service.
Thanks again garret,
Larry
