Review: Noopel vs Sabre vs GE window alarms - Summary: Noopel & GE recommend, Sabre DON’T recommend. I live in a mixed urban neighborhood and my new apartment has more windows such I shopped for additional alarms to augment the Sabre & GE brands I already had buying first more Sabres, then because the Sabre units performed badly I purchased several Noopel units. I’ll start with Sabre Wireless Home Security Alarm as I have the most of these. I purchased them on the basis of desertcart reviews at two intervals a year apart such I have experience with them. I found them WEAK & VARIABLE. Even on the stronger units the alert isn’t enough to wake me if sleeping, many units have such a weak alarm that I might not hear it in another room with the TV on. Sabre’s weakness prompted me to return to desertcart for an alternative and I bought Noopel Magnetic Entry Sensor as a replacement. BIG difference, these you can hear at a level likely to chase an intruder off and alert the neighbors to turn on their lights. I liked these enough that I repurchased more as Sabre replacements. GE Personal Security Alarm – Earlier I had purchased a pack of GE’s from desertcart and have over a year’s experience with them and would recommend. They still have a loud shriek and would serve their purpose to scare an intruder and wake you to the danger. ON/Off placement. The 3 brands differ in where they locate the on/off switch with Noopel and GE placing theirs on the outside for easy access. Sabre locates their switch on the INSIDE such you must take the battery cover off to access the switch – both awkward and easy to lose your batteries. The Noopel & GE placement is superior in my judgment. Overall I’m disappointed in the Sabre’s I bought. In fairness I tried new batteries and purchased more than one set a full year apart – no volume, no deterrent. Noopel is new and I can’t comment on longevity, but out of the package – they WORK. GE I have long experience and they have both better design & better performance than Sabre.
Review: Parent’s of Autistic Kids must have! - I am a social worker who received referrals from CPS for families that didn’t need CPS involvement, but needed help with resources in our Community. Many of our clients were families with autistics kids. I developed kits to include these alarms along with replacement batteries for the alarms. I helped install these above the door frame if possible. The alarm is very loud and alerts parents if the doors open. Beware some kids will try to use a chair to turn off the alarms is the reason I tried to install them at the highest position possible. I would not go to sleep and rely on the alarm to wake me up if my child tried to open the door. But it does provide an extra layer of security to protect and monitor your child. Highly valuable for autistic parents.

### ⭐⭐⭐⭐ Perfect for an Inexpensive Window or Door Alarm
*by R***. on June 28, 2024*

Bought these to be in compliance when we added our pool. They are easy to apply, work well (very loud!) and were perfect for what we needed them for. However, one already lost it’s adhesive and fell off.
