If your budget is more Motel 6 than it is the Ritz Carlton, hotel security may be a major concern. That’s where the Hotel Door Security Alarm comes in.
Just hang it on any metal doorknob in your room and it will emit a loud alarm ( 105db ) whenever someone touches the doorknob on the outside. That’s what you call instant piece of mind.
Plus it’s great for scaring the hell out of the maid.
