I tried Ring in the past, and after struggling with it for a few days (probably got a lemon), decided to return it and forget about changing the doorbell. The iDoo was pretty straight forward to setup. The user manual is good, it could be a little better. Before removing the old push button switch, I decided to test it and experience the product. The available micro USB input in the back of the device made this process pretty easy. I was able to get the software installed on my phone, connect it to the device, configure it and test it while seated at my desk.Once I was satisfied with the device and the software, I removed the old switch from the outside wall and installed the device. The installation would have been a lot easier if the back plate screws were positioned at the same location as the standard doorbell switch, but they weren't. I had to drill a hole in brick - which needed a carbide-tipped masonry drill bit, fortunately I had one and was able to drill a hole and mount the back plate. That was the hardest part. Installing the chime kit on the mechanical bell was pretty easy. Once the doorbell wires were connected to the front panel and it was attached to the back plate, I was in business.Since I already had the app installed and configured, it started working. I had to do some tweaks to the app settings - adjust the video quality, setup additional members of the family, setup motion alarm etc. I also had an old MicroSD card that I was able to repurpose to use in this device. Beginning to end, it took me about 30mins.This a good, budget-friendly device that gets the job done. It has only been a day, so too early to tell how the device will hold up over time. I will post updates in the coming weeks.
