The ease of use is amazing! It's so easy that I can do it all myself with some help here and there (especially when using our VPN). You could spend hours trying different settings but you won't get any better results than what this software provides in just under 30 seconds flat.. Nothing at least not yet anyways :) We have many servers/devices connected directly via ethernet cable which are very hard to find if they're located behind another device like an IP phone etc - especially since we don´t want them broadcasting their mac address publicly anyway. With rumbler I only had one instance where i needed my colleague support because something was wrong during configuration; otherwise everything works wonderfully out of box.
