The ease of use, it is very user friendly to anyone who uses their device for any task that may need remote control over home automation devices such as lights/heating etc., It's always been great because we never had issues in previous services I have used but this one has definitely raised its standards by miles! Great customer service too which helps keep me coming back each time they are needed during an emergency situation!! They also do not charge extra fees if there was no internet connection available- what more could i ask? Nothing at all so far other than excellent workmanship from every employee involved throughout our project - everything went smoothly without issue once installed (except some minor tweaking required due to local code differences).
