The ease of usage from start to finish is top notch! I have been using this product for about 4 months now & it has made our life easier by leaps an bounds (literally). Nothing at all that we dislike here so far although they say there may be some minor glitches or issues but nothing too bad either way once addressed its fine again - no problems yet :) Highly recommend!! As mentioned above everything was easy peasy just get over those initial hurdles then what's not really anything other than having patience while waiting during setup/initialisation etc before getting into actual useage phase where things are smoothed out even more!
