        Riots are going on. Need a mini remote alert to keep home safe. So I bought this cute mini sensor. It is mini and white with good concealment. I can remote control it with my cell app. Pretty convenient~

        I installed this sensor relatively simple. You do need to slide down the back cover to expose the on/off switch and the reset button. It works very well.
  • Poor instructions for first time install.. then great

     The instructions weren’t very intuitive for someone setting up wireless sensor for the first time. Although there was a note to setup app first, going by the flow of the instructions, I stuck the tape to the back of sensor. Just to realize in next step that the parts on the back are needed for app setup. So took the tape off, only to find the back doesn’t exactly match the diagram. But being the only recess there, got that it would be the reset button. However, it didn’t show any sign of budging when pressed with regular force for a typical reset button. Taking a risk of breaking the notch, when pressed hard with the blunt tip of scissors, the setup light came on. NOTE: Moving the on/off switch to on position does not turn on any light.

    After that the setup was quick, won’t even need all the other screenshots in the instructions. The sensor was recognized and setup instantly and started popping up the status notifications as the magnet would align/ move away.

    The adhesive tape holds good - it stood up to my earlier mishap of sticking and peeling. Love that it is rechargeable with USB. Charged it before sticking on the door, so hopefully it would go long way. It says to peel it off and recharge when needed. Wonder how many times the adhesive tape could be reused.

    I had a decorative frame that had little space to accommodate the magnet part, so chiseled it out a bit and the thin part fit good. Read that I could have just taken out the magnet inside the casing and stick it to the frame too but went for the complete look :)

        I bought this to see how I would use it and I never noticed how many times my front door opens before.

        So far so good. It’s very small and easy to install. I installed it on my window, the color is perfect match with my window.
