Just wondering if anyone has any feedback on the Hypoband devices available which claim to alert you to nighttime hypos? My 10yr old has nearly 5 nighttime hypos a week & never wakes or realises he is low. We have tweaked his insulin levels & tried everything but even his consultant is bewildered by why it is happening. At present my husband & I take turns monitoring him throughout the night but just wondered how effective these devices are before we spend the money? Thanks in advance for any help!!
