  1. Great except for the little bright teal light that is always on Review by Jane
    Overall Satisfaction

    It works perfectly, and is amazing for use as a cell phone alert. I also have been using it as an alarm clock, by setting the alarm on my phone , then setting it to vibrate. The actual color of the unit I received is a lot more teal than green, but luckily I love teal. :) The only complaint I have is that the light that indicates the unit is on is very bright and stays on as long as the unit is on. As a deaf person, I am used to lights as a way to wake up, and much prefer darkness to sleep. It's taking a lot of getting used to, learning to sleep with this on. It's like having a teal nightlight beside my bed. (Posted on 11/9/2017)

  2. Ingenious Design -- But Underpowered Review by Matthew K.
    Overall Satisfaction

    This system is ingeniously designed to work with any cellphone that has an adjustable vibrating alert for voice and data calls. It responds perfectly to my iPhone 5 once I've configured the phone's notifications to use the "vibrate" mode.

    A serious flaw is the SMS cord, which has to be attached to the phone's headphone jack. The iPhone 5's jack is on the bottom of the phone, so the phone has to be placed sideways, in landscape mode, in order to use the SMS cord. This blocks some of the flashing lights.

    I also found the unit's flashing lights and siren were not bright or loud enough to rouse me from a deep sleep, so I've connected the unit to a CA-360 unit, where it does a fine job as a wireless adjunct. A simpler and less expensive wireless unit that allows a vibrating cell phone to alert the CA-360 would have been the ideal purchase for me.

    ***Manufacturer's response**
    We thank you for your purchase of our Central-Alert Mini System. The system alerts user on incoming mobile and SMS calls by detecting phone vibration. Phone vibration longer than 2 second is needed in order to detect. The short SMS cord that came with the system is meant for use with an older mobile phone. Many older phones provide no vibration on SMS call; or their vibration may be too short and can not be detected.

    Since you have a smart phone (iPhone or Android) you don't need to use the SMS cord. You can easily customize your iPhone 5 to have a 3 second vibration on a SMS call. This will activate Central Alert Mini like a regular mobile call. Your phone should now be placed upright and not blocking the flasher. Please refer to Page 8 of our product manual on iPhone vibration customization.

    We appreciate you giving this a try and inform us on any comment. (Posted on 5/6/2014)
