I have dozens of TP-Link KASA products installed in my home, including a dozen smart plugs (majority only get seasonal use), nine on/off switches, one 3 way dimmer, and five of these dimmer switches.
They are well made, an unbeatable value when on sale, and straightforward to install (note that all TP-Link's Kasa switches require a neutral wire - depending on when your house was built and how the switch boxes were wired, you may or may not have a neutral available in your wall switch boxes).
These connect to the 2.4Ghz band of WiFi - note that these switches can end up out of range of your WiFi if you have your access point or router poorly positioned in your house and/or you have a substandard access point or router - I have no connectivity issues with an access point located on the ceiling of my first floor in the center of my 2 story home - be prepared to up your WiFi coverage if you're serious about having a smart home - I have a separate IoT VLAN defined on my router and provisioned to the 2.4 GHz band of my multiband AP to keep my IoT devices off of my home network. A single AP covers my 2700 SF house, for both the 2.4 GHz band IoT devices, and the 5 Ghz band human facing devices on my home network.
These switches are large, as are most smart switches - I've found they install easily in the modern plastic switch boxes in my renovated kitchen and family room addition, but can be a tight fit in the original steel switch boxes in the remainder of my 1963 vintage home - I have taken to replacing the original steel boxes with new "old work" plastic boxes, and will spec the extra deep "old work" boxes if the stud cavity allows for it - this solves the space issue, and again if serious about a smart home are some of the things you need to do to be on board.
These switches are "Decora" style and are activated by pushing the bottom of the plastic paddle for both on and off functions - while the ergonomics are a bit different than a standard "dumb" Decora switch, I like them, and honestly I use voice or routines to control the switches to the point where the physical switch interface is a non-issue.
In multi-gang box situations, I have taken to replacing any "dumb" toggle switches with corresponding "dumb" Decora paddle switches for those switches I don't need smart functionality in, in order to keep the look consistent. I have had no issues with the "yoke" depth of these TP-Link Kasa switches in terms of being able to install standard wallplates - I have replaced my old steel "Mulberry" plates with screwless plastic "Claro" branded Lutron wall plates for a nice clean consistent modern look - see photo. Steel plates are a no-no BTW with smart switches - they obstruct radio signals no matter what tech you are using - WiFi, Zigbee, Lutron ClearConnect etc.
I also use Wago lever style wire nuts for the end point connections for the wire leads coming off of these Kasa switches - they save some space and can also save some wear and tear on the house wiring rather than have to untwist pretwisted and wire nutted connections to make changes and/or additions in the future.
I have dozens of Alexa routines set up using these switches - the switches can be used to initiate an integration, unlike my Lutron Caseta switches, which can only be acted on by a routine, they themselves can't initiate a routine. These also integrate with Home Assistant.
These have been dead reliable for me in terms of connectivity and responsiveness. Most of the negative reviews are unwarranted IMO.

FULL REVIEW Kasa Smart Dimmer Switch Smart Switch

Throw away the cover
First off the switch works as advertised, but the first thing that hits you is how hard it is to take off the cover plate. After that the Kasa app does a good job going through the installation process. However; it was impossible to reinstall the cover. I suppose I could have hammered it on at the expense of possibly breaking it, but looking at it closer I discovered the original screw on cover would work just fine and also look like all the other ones around the house. So bypass attempting to reinstall the cover and just use the screw on cover that was originally there. Otherwise, connects to app an Alexia flawlessly.
