“I bought a new computer from jbhi due to Windows 11 compatibility. Maxwell from Reliable Computers came out and within a very short period of time configured everything from my 9 year old model to the new one. No stress. Repeat- no stress. Maxwell was uber efficient and helpful. Another issue a day later was a new printer that needed to be connected caused me an issue. Vineet from the same company via the phone solved this problem over the phone. Summary: As their name says- reliable.,A stress free experience and I have no hesitation in recommending their services. In 12 months I am getting them to install Office 365. 5 Star Service.”
