Given the cost, I was shocked at how well this timer worked. It has exceeded my expectations so far and if it lasts long (just a few months now) I will definitely be buying more. I bought this to replace the noisy, broken mechanical timer used in the lizard tank to turn the night light on and off and it worked really well. It was easy to set up with my Wi-Fi and the app works well, although it can be tweaked to be a bit more intuitive. The only thing I found in the app is that they need to set up an easier on/off schedule instead of having to schedule one on and another off. Apart from that, I hope they only improve that it works with two Wi-Fi networks. Right now, at least my model only works with 2.4GHz WiFi, so I have to keep in mind whether I'm on a 2.4GHz or 5GHz network when using the app. Also, I found it easy to set up and turns on and off on time. I'm curious if it can work well with Christmas lights in the near future. So if it continues to work well I will definitely be buying more.
