Relatively easy to install for me and I am not an electrician. Biggest issue can be space in the switch box. Works great with my Google Home setup. Bought two and will buy more.

Contacted customer support and talked with Justin Abolucion concerning reestablishing my kasa light switch to my new router. I had tried to do it and could not. Justin was very knowledgeable and led me through the difficult process very quickly and professionally. Great experience.

These work great. Once you complete the initial setup, it works throughout the range. No issues on remote access or set programming.

I have multiple standard Kasa smart switches in my home and decided to give the dimmer switch a try. Based on the other installs I figured this would be easy. However, the switch box is much larger than the standard switch to the point where it's difficult to install in a crowded electrical box. I had a very difficult time cramming this into the electrical box because of the size. I'm not sure why it needs to be so much bulkier compared to the other switch. Besides from that, once I was able to complete the install, the switch works great. Unless you're specifically looking for dimming capabilities, I would just stick to the standard Kasa smart switch.

The light switch works well and was not that hard to install as a not being an electrician. It controls LEDs etc. I don't have Alexa but it works with Siri and my iPhone.
