These items are awesome. I love the small size, and the insides is well constructed. They did a proper design. The motion sensor has jumpers for setting different addresses for different alarm systems (no information though), a jumper for test mode, and a jumper for disabling the LED. The remote control is a nice size, feels solid. The doorbell button is a good size, but not too large. It feels comfortable to press. It is not waterproof, but it is fairly water resistant. I'd suggest smearing Vaseline (petroleum jelly) on the inside. There is a silicone sheet covering the LED hole and separating the PCB from the plastic button, but no seal on the perimeter where the case joint is. The PCB is well designed. This is the only wireless doorbell I've ever had that reaches from my driveway gate all the way to the middle of my home. The sound on the alarm control panel is nice.

I bought the Digoo 433 MHz Window Door Sensor, together with a Digoo DG-ROSA 433MHz wireless DIY Standalone Alarm system. It all Works perfectly as advertised. I use the alarm system to secure a boat, at a distance of 35 meters from my house. Therefore I needed more range. So I soldered a piece if wire of 35 cm to the unit (35 cm = 1/2 Wavelength, which is 70 cm). This piece of wire functions like an antenna and effectively doubles the range. (See photo, to see where to solder the antenna wire to the Door Sensor unit.)
