I bought these for my mum who wanted to find her walking stick and keys if she lost them. We downloaded the app to their Google phone, installed all 4 and then tried them one at a time. They all continued to disconnect from the app when they were 15 to 20 feet away from the phone. You basically have to walk around the house waiting for everyone to finally connect to the app. Then you can press a button in the app to trigger the alarm. One of them didn't even connect to the app when we hid them about 25ft from the phone. pretty much useless for its intended purpose. One of them had an alarm that wouldn't go off no matter what we did finally pulled out the battery. All 4 did not have the selfie part to take pictures working. I thought maybe their phone was the problem so I installed the app on my Iphone 11 and encountered the same issues. Pure garbage. You get what you pay for.
