Easy to use just plug in and turn on

Its only been a couple of days so maybe just maybe its too early to review this product but had a mouse under the sink area in my kitchen tried traps and poison with no licked at allbefore i went to bed scattered salt a thin layer over the work surface so i could see if and where this mouse had been and sure enough his footprints testified to thisi plugged this little gizmo into the socket and to date not a sign of my unwelcome lodger no footprints and no mouse droppings so fingers crossed he or she has vacated the premises and i can get in with finding and sealing up the hole he entered bywill update in a week or so but so far its looking very goodi did read the reviews before chancing a small amount of money and it appears to have paid off
