I've been a customer of HCS for 8+ years. I'm always provided an accurate estimate, the staff is courteous, professional and extremely knowledgeable. In addition to technical service, they sell refurbished computers that are top notch and less expensive than investing in a new product, which has always worked well for me. Also, they have a monthly service that monitors my computers for viruses, malware and lets them know when something isn't working properly with my computer hardware. I've spoken with other clients who've used them for a long time as well, and they share my enthusiasm for this business!
