Had an excellent experience when I bought the phone system for my company. This is a large purchase for any company and there are a lot of options to think about. After looking at several companies, Tech Optics won my business. They were very attentive to my needs and were able to see vision of where I want to take my company in the future, and took that into consideration when building my quote. Installation was seamless and my company experienced no downtime during installation. I highly recommend this company to anyone.
