Review on Wsdcam Wireless Door Alarm With Remote 2 Pack, Battery Included, 105 DB Loud Pool Door Alarm, Wireless Door Open Alarms Sensor For Kids Safety Home Security by Jon Russell

They work great and you can use both of them with any of the remotes.I wish the lid to replace the batteries would be a little harder to access though. Just a screw there, would be perfect and it would make it really hard for any intruders to remove the batteries.The ring bell however is way too loud. You'd definitely want the alarm to be loud and in that sense it's perfect, but the bell sound is too loud. You don't need the bell to alert you of intruders (that's what the alarm is for), you need it to just let you know someone just opened the door, but without being so annoyingly loud.Overall is a good product though.
