Client Quotes

We have worked with Afinitek for 4 years and have bought Cisco equipment from them for customer projects we are working on. So when one of our large public sector clients came to us to ask us to support their Cisco environment of over 70 devices we employed the Caretek service from Afinitek. Caretek enables us access to Cisco software updates which we deploy to all devices and in the event of a device failure we know a replacement will be sent direct to our customer site within the SLA timeframe we signed up to. Total piece of mind at the right price.
Andrew Thomas - J-Co Ltd
Afinitek always provides the most competitive costs for our HP requirements, combined with an excellent service and prompt deliveries enables us to repeatedly win business and exceed our customers expectations.
Matt B - C-verge Net
The Caretek support gave us peace of mind in extending the life of our hosting platform when we migrated from one data centre to another. We had an occasion to call out an engineer to replace a failed hard drive. The call was handled promptly and professionally and well within the SLA, It enabled our hosted environment to continue running. I wouldn’t hesitate in recommending Caretek, It’s a great service and very sensibly priced.
S. Bell - S-Bass Software Ltd
We have purchased several Cartetek support packages for our clients networks. It would be impossible for us to hold stock of all the parts that make up the networks we support so really like the fact that we know replacement parts will be sent when we report a fault. It allows us to focus on what we do best which is supporting the customer and not sourcing replacement parts. We like the fact we can buy IT hardware from Afinitek too, it keeps everything all under one roof.
