Wireless Wedge Shaped Door Stopper Alarm

Was going to use it on vacation but ended up not using it at all. Exterior wear due to storage. 3 Sensitivity Levels - Low - Medium - High, with an adjustable sensitivity switch on the side. Also works as a wedge to prevent door from opening when powered off. No installation required. Requires one 9 volt battery (not included). Lightweight, portable & easy way to add piece of mind when traveling or working alone. Extra loud alarm. 120 decibel alarm sounds when pressure is applied to door stop.
