Good support
Have only had product since 1st April but does not work all the time. It is intermittent and cannot be relied on! On product details it states 90 days to return/replace but Amazon only have 30 day policy. No way of contacting seller either! Editโฆ.. managed to contact seller and they replaced item even though Amazon only gives 30 day replacement seller was good to their word. Product replaced, working well. Lots of follow up and support from seller. Would definitely recommend as after care is amazing. Thank you โบ๏ธ

Stopped working - returned
Great at first but stopped working after 3 months with the plug chime going off for no reason even with the sensor switched off. Also states it takes CR2032 batteries but the model we received takes CR2450 which we now have an abundance of after returning the faulty item.

Alarm
Really decent and work brilliantly, I found it abit confusing at first setting it up but once ypu get the hang of it, its pretty easy. Loud enough to hear it anywhere in the house. Adhesive is long lasting had it awhile and still up with no signs of coming down. Response time quick.

Cognitive decline and audible alarm.
Easy to set up and works a treat, very good for notifying when elderly people try to leave the home.

Brilliant for keeping people/kids safe
Bought for my in laws house as my FiL has mixed dementia and is prone to leaving the house. This now let's my MiL know when he opens the door. There are a number of options for the music/ringtone it plays when the door opens. It also has a volume control and was easy to install with the adhesive pads supplied. Would also be great for using with kids.
