Horrible — he ruined my Apple, it took over a month, he ordered the wrong part to begin with telling me there are three mother boards for that year Apple with one digit difference,I asked him, "did you READ the numbers?" He went into what false claim makers do, talk over the question as if I didn't ask it.He KNEW I was cycling across-country, on a budget and with time constraints — ordered a second part — it didn't work, ordered a third but COULDN'T postpone his vacation for 12 hours (to Albuquerque) but had already ruined my life.With every claim there is at least one lie; his lie, that he is competent. He trashed my computer and now I have to get a new one. Avoid this guy like the plague. HORRIBLE_THE WORST!!
