My biggest gripe with this dimmer switch is that it is difficult to install due to it being significantly larger than most switches. If you have a small electrical box or an electrical box with multiple switches within, this switch will be quite difficult to install.
Overall, this switch works great if you can bend the wires around in the box to install it. I've had no issues with setup, and it works perfectly.
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.

These have been dead reliable for me in terms of connectivity and responsiveness. Most of the negative reviews are unwarranted IMO.
Installation: 5 stars, super easy and much better in my opinion than the WeMo switches. Main wires screw onto to the switch plate, and a couple of wires run off to attach with nuts. WeMo had all wires run off to attach with wire nuts which resulted in large amounts of wire and clutter behind the switches making them much harder to work with.
Application: 5 stars, switch was immediately recognized and I had no problems with the application. Unlike the WeMo switches where I had several that had significant problems connecting, and they constantly disconnect. The Kasa switch has had a couple of times where the physical switch didn't work for a short period of time, but the app has always worked even when the switch didn't, and then the following day the physical switch would again work. Not sure if that is the result of a bad switch or if something else is going on, but ultimately it is a relatively minor issue as I can always use the application to turn the lights on or off if needed.
Wireless: again the setup and connection were easy, and I haven't had any problems with the switch staying connected to my network and always being accessible via the application. I have loads of problems with this on the WeMo switches.
Design: The design is much more well thought out from the wiring to even the physical function of the Switch than the WeMo version. WeMo uses a capacitive touch plate that runs the entire length of the switch. This results in the dimmer level constantly being change, turned off, etc... whenever you turn the light switch on or off because almost the entire switch is capacitive touch. Kasa on the other hand has their dimmer buttons at the very top of the switch so they are never in the way but are very easy to access.
Quality: Quality seems to be on par with the WeMo, but the design decisions were clearly well thought out. If feels like someone actually tested the Kasa Switch, while it feels like no one actually ever tested the WeMo switch design of they would have easily seen and addressed several of the blatant issues it has.
Note: there is one oddity with the Kasa switch, you may consider it a good or bad thing, but when turning the switch on/off there is a slightly delay (maybe 1-2 seconds). It caught me off guard at first and made me think the switch wasn't working properly. I'm still on the fence on whether this is a good thing or not, I think I prefer the instant switching action, but I can see why some people might prefer the delay and once you realize it is there it is honestly not a major issue.
The Kasa Dimmer switch isn't perfect, there are a few oddities to it, but it generally functions well, it seems to be far more well thought out than the WeMo switches and is significantly more reliable as a "Smart" switch. If you are trying to decide between Kasa and WeMo, don't wait, go with the Kasa switches, they are significantly better in almost every way than my WeMo Switches have been. At some point I will be replacing the rest of my switches with the Kasa Switches and removing WeMo entirely from my house as they just have way too many problems with them.

FULL REVIEW
This is my 7th Kasa smart device and the first smart light switch I've purchased. As someone who is not very handy with household electrical, I found the guided installation instructions in the Kasa app absolutely incredible. The app walks you through every single step with total clarity - there were no instances where I had to guess or try to figure out what the app was asking me to do. Installation took somewhere between 30-40 minutes which included time that I spent running down to our circuit breaker. I was able to complete the installation by myself without any help.
Once the switch was installed, the Kasa app made getting the device linked to my wifi and smart home a breeze. It took maybe one minute to get everything linked up. The setup process was straightforward and easier than I expected.
The only oddity that I noticed was at the setup step for the calibration of the dimmer. During setup, you will be given a slider that will allow you to calibrate the dimmer levels based on the type of bulbs that you are using. The slider shows the lowest dimmer range for both incandescent and LED bulbs, however as I tried to use this, I noticed that my dimmable LED bulbs did not respond to anything but the largest changes on this scale. As I would change the minimum threshold for the dimmer (either up or down), there was no noticeable difference to the brightness of my bulbs. In practice, this doesn't seem to make much of a difference to the actual dimming functionality of the switch.
Also, it doesn't appear that you can control dimness using voice control with Google Home. To change the dimmer settings, you will still need to either control it from the actual switch itself or open the Kasa app on your phone.
Overall, I'm very pleased with this switch. It makes a nice, affordable upgrade and like my other Kasa smart home products is so easy to set up and use. 100% recommended.
