UMMMMM, HOW AM I EXPECTED TO TEST THIS? IF I am allowed to only set one alarm I do not see how I can test your minimum 150 foot threshold. I want something that will alert me when I go from the house to down the street. However without a base I can not see how true that 150 foot rule really works. Also, what is someone wants to try it for something else? What are you going to do with ONE ALARM? 3.99 a year is not a lot but still do not want to waste it if this does not work. You should have a free 24 or even 12 hour unlocked trial version… or at the very least be able to add 3-4 alarms before having to pay. So weird….. boooo 😛 ✌️ Also, not able to see other peoples reviews?? Super booooo
