I like that they are very responsive to our needs, whether it be for software or hardware upgrades/deployments - we can count them as one-ofs! They also have great support staff who will go above & beyond what you would expect from any vendor when working with your business's technology assets (hardware / servers).
We've been able use their team since day 1 without issues; which has made us feel comfortable about having more complex projects through out my tenure at this organization now compared too other providers where there were many hiccups along th way requiring constant communication back an forth between myself + customer service reps etc..
