The performance is great, it's easy of use with all devices. It has an app for both iOS & Android which makes life easier when you're away from your computer. I have not had any issues at this time but if there are problems I would contact them right away as they respond quickly to my concerns! We've used in our office for about 3 years now. It works well with wifi. Sometimes we get dropped off the network. If you need more speed than just web browsing then this may be unsuitable for what you want however, otherwise, it does work very well. Having access to internet anywhere without having to rely on wired connections or data plans.
