I like that it is compatible with my Google Home, Siri or Alexa devices to add convenience in using this device as well when we need our keys access at home/office without carrying them around all time! Nothing too dislike but can think of nothing really either since its very convenient especially during working hours where you don't want carry key everywhere just use salto so no worries about losing one while traveling! Definitely recommend because if anyone looking forward an easy way tp gain entry then look into Saloto Key which i personally used few months ago now not sure what they are doing these days regarding their products? They have been improving over many years from initial design till current day version? If someone having trouble accessing office building /home through door locking system maybe best option would be go thru sales representative before getting anything installed otherwise may ask friends who had previous experience how was install process went.
