We use this product at work for our VPN connections. It is easy to install using their software which works well once installed. Their support team are very helpful when you have issues so far as I've experienced they respond quickly via email or phone call. They also provide excellent training materials if required during setup of your system. All good! Support can be slow sometimes but overall it's been fine from what we experience here - some days just slower than others (we're talking UK timezone). No real complaints about its functionality other than perhaps more options could maybe make things easier/more customisable? But all these comments apply equally across most solutions out there anyway?! Just get one try before buying anything else!! Use them where possible because of ease-of-use / cost effectiveness compared against similar products available elsewhere.
