Just purchased a 2017 iMac and related products, and had lots and lots of questions - since my "old" iMac is a late 2007 model running Mt. Lion! The service was excellent - emailed questions promptly answered both by email, and with follow-up phone calls. The "guys" were patient, carefully explained everything, and I never felt pressured to buy. They were pleasant and eager to be helpful. Can't wait for my new iMac to be installed - and have every expectation that the service that day will be just as good.
