平均5.0 星 Great break-in deterrant, very loud! 2016年3月24日
评论者 DS V - 已在美国亚马逊上发表
包装数量: 1 已确认购买
We bought these as just one extra safety precaution for our house. We ended up putting them on our basement egress windows just in case someone decided to break in. We will also put one on our storage area downstairs as well.

We did a test of these when we first got them, and man are they loud! Which is great when you're looking at items like this. My husband went downstairs and tested them out, and even sitting in the living room watching TV with all doors to downstairs shut, I could easily hear them go off as he tested each one.

These seem like high quality little protection devices. They come with super strong tape to stick to whatever surface you want them to go on. They stay secure and don't move. However, when you take them apart (such as open a window or door) be sure to plug your ears because there is no way somebody is sneaking in.

Pros: Good loud sound, very high quality 3M type tape to secure, easy to install and set up

Cons: None. We may end up buying another pack of these.

These Little Battery operated alarms are Great for what they are, Sure they arent ADT alarms but they do give you a decent amount of Peace of Mind! With these little alarms and a security window sticker and Securtiy Alarm front yard sign you can have a decent amount of Peace of mind for Home security Protection! I highly recommend these Little Alarms for anyone who needs some Peace of mind against Burglars, The alarms are Loud, I can say Both the Chime and the Alarm are Loud and i used these GE alarms for my Basement Windows and they work perfectly! Just my Honest Review for this Product, Hopefully i was of some help to someone interested in purchasing this Product.

平均5.0 星 Inexpensive and do the job 2015年12月25日

These are so great -- easy to use -- just stick on with the double-sided tape and switch to alarm, chime or off position.
The chime chimes once but the alarm siren stays on and really alerts you to a window or door opening. I have gotten these for all my windows. Button batteries are included and can be replaced as needed. Instructions say they work up to a year. There is a battery test button also. The decibel on these are way louder that most other company's. I can hear these all over my 2200 square foot house.

平均3.0 星 The two of the four which work, work well. :-/ 2016年3月15日
评论者 R.W. - 已在美国亚马逊上发表

This product is a little disappointing, but about what you might expect for the money. They feel like cheaply made toys and that reflects the quality of the electronics inside the units, half of which did not and do not function properly. They are small enough to use on most window frames although obviously some thought must go into exact placement. I discovered that, to avoid them being easily seen from the outside, I can place them on top of the lower half of double hung windows, completely hiding the unit from outside view (preventing the mode switch being seen from the outside). This also reduces the probability of the unit falling off (in the event of the adhesive tape's failure) because it is lying flat on top of the frame.

The volume is adequate and the alarm can be heard from one end of our rather large house to the other and continues sounding until turned off at the switch or the window is closed. The chime is almost as loud and, of course, not as obnoxious and only sound for a few seconds.

The reason for only 3 stars is that two of them do not function properly. They've been installed for about a week. Disappointingly, one of the four units' alarm mode failed "out-of-the-box" and another unit's alarm mode will only chirp and not continue sounding if the window is raised quickly. This creates uncertainty and a lack of confidence in the product having a long service life. We'll see and I'll try to remember to update my review after they've been in service for a while. I plan to order another package for I'm interested in whether the percentage of non-functioning units will be the same.

Also, these will not readily work on most residential doors due to the offset from the frame molding to the surface of the door. A supporting block could be affixed to the door which would place the alarm unit in juxtaposition with the magnet. Some modification to decorative molding would have to also be made in order to affix the magnet securely.

Having done several tests, I'm reasonably confident the ones that actually work will provide adequate warning in case of unauthorized intrusion and will adequately support our home defense strategy.

平均4.0 星 Loud Enough - Simple Security Notification 2015年5月26日
评论者 Richard L. - 已在美国亚马逊上发表
包装数量: 1 已确认购买
I'll give this alarm a little better than okay rating since they are pretty inexpensive and are easily installed. The chime setting is quite loud but only rings like a doorbell (ding-dong) where the alarm setting continues to "wail" (loud enough) until the contacts are, again, joined.

Each unit comes with double-sided adhesive to attach the pieces adjacent to one another. They don't have to be exactly parallel but the arrows on each piece must line up within 1/2 inch to each other for proper operation.

Overall, these are a good choice for simple notification of a window or door being opened and are easily portable for traveling.
