These work perfectly for me. Set up is straightforward (details follow). I love my new bulbs.
These bulbs are EXACTLY what I was looking for. The soft white color is perfect for a bedroom during wind down and bright enough to do work by. The attached image does not due them full justice). I highly recommend them, if you have a 2G network available. Note: Your mobile device will NOT have to operate on the 2G network. Just the bulb, but be sure you have the network password handy. The instructions that come in the box could be clearer to be sure, but it’s straightforward: 1. Install the KASA app on your mobile device (if you don’t already have it). 2. With your mobile device on its usual network, open the Kasa App (make an account or login). 3. Select the plus (+) sign 4. Choose “Device “> “Smart Bulbs” > “KL100 Series 5. The App will set you through the rest of the setup in detail. There are just a few steps (follow from within the app but this is FYI) A. Power OFF your lamp and install your new bulb. B. Power ON your lamp and wait for the bulb to blink 3 times. B. Connect your device to the BULB’S Wi-Fi network (temporarily). Each bulb has its own unique name that starts with TP-Link (something). C. Return to the Kasa app (It will prompt you at the top) D. Assign the bulb a unique name and location and you are good to go. **Important** Any manual light switches must be left “ON” and any manual dimmer controls must be set to 100% in order to control the lamp from your app. Voice control is available from Alexa and Google Home following instruction from those suppliers. I haven’t tested Google Home but I have 3 bulbs working perfectly from the app (Image attached) and Alexa (image attached). I’m extremely pleased.

Easy to Connect Smart Bulb That Works Seamlessly with Alexa
When I received these bulbs, it was a minimum amount of time spent to add them to the software app and Alexa. I went through the quick setup 1 time with each bulb and shazam........they were set up and working perfectly. Some people reported that they aren't bright enough, but I think they are perfect with a warm glow. I previously used Sengled brand bulbs and I would not recommend them to anybody. They were CONSTANTLY disconnecting or wouldn't show in Alexa. Numerous times I received a message that their software was down. I'm happy to replace them.

Perfect for dining room fixture
Saw these on sale and decided to give them a chance. Glad I did! This was my first foray into smart lightbulbs. They helped solve a particular problem in my apartment. My dining room light fixture is controlled by a non-dimmable Z-Wave smart switch. I don't have control over the hub, so I can't replace the switch. Not without incurring the wrath of my landlord, anyway. Not being able to dim that light was miserable. Smart bulbs ending up being an ideal solution. The Kasa app works great, and is almost as convenient as a physical dimmer. Sometimes it's better, since I don't have to get up from the table. The app *does* allow three bulbs to be linked and dimmed as one, which is essential for my application. Setup was easy as well. Each bulb starts in access point mode. First you log into each one and give it your Wi-Fi credentials. Then you add them in the Kasa app and group them as needed. Very slick. These also excel as lightbulbs. Color temperature is perfect. The 90+ CRI rating is believable. Dimming is smooth and incredibly fine grained, with no flickering at lower levels. I can dial in anything from candlelight to full light suitable to work by. I've been using these bulbs daily for five months, with no issues. I'm very pleased with them and would buy them again in a heartbeat.

Convenient
★★★★☆ These smart light bulbs work well and were easy to set up. They connected without much trouble and respond as expected when using the app or controls. The brightness is good, and it’s nice being able to adjust the lighting when needed. The price was a little high, but overall they perform as intended. A solid product that adds convenience to everyday use.

Solid dependable smart lights for use with Google Home
I have used C by GE smart lights with Google Home for many years but they sporadically and often would not respond to commands. However, I noticed smart devices that were by other manufacturers still responded during these annoying outages. So, after just dealing with this undependability for far too long, I switched all of the C by GE lights (20 bulbs) with these Kasa lights. The setup was a breeze and they simply work. The Kasa app is easy to use and the devices easily connected with the Google Home app. Going on a tangent here and ranting about the buggy nature of Google Home. It often goes offline and then magically comes back online. Pretty frustrating. Even more so is the fact the Google Home app doesn't give you an easy way to remove old devices (like the 20 GE bulbs) from your home setup. They literally removed the "remove" option from the device settings. I mean, WTF? Who thought that was a good idea at Google HQ? I had to create a whole other "Home" then move these old bulbs over to that new bogus home rather than being able to simply remove them. Anyway, getting back to these Kasa lights... They are great and I would highly recommend them to anyone that is sick of their lights from other manufacturers not working consistently with Google Home.

Decent basic smart bulbs
I like that I can change the brilliance and brightness. With the app, it’s easy to schedule however the scheduling is limited compared to Tapo. Responds well to Alexa. Fairly easy to program. The Kasa app can merge with the Tapo app can merge with the Alexa app however there are minor things that have to change in the Kasa app. A gradual turn on is not smooth. It comes on in jerky moments no matter how short or long the time. One thing to note is that if your internet goes down, they won’t come on. Even with a schedule. If you need to manually turn them on, they turn on at the power last activated (25% etc).

Sin problema
No me dio problema conectarlos, y ponerlos con Alexa, dan buena luz, yo los puse para un cuarto de televisión, lámparas de pared, me gusta esta marca porque tengo ya como 7 años con 3 que puse afuera de la casa y no me han fallado y duran prendidos casi toda la noche como desde las 7 o 6pm los programo para que vayan bajando la intensidad mientras pasan las horas hasta que se apaguen a las 4 de la mañana y el recibo de luz sin problema, no hubo cambios desde que los puse, de verdad que no gastan!

Kasa Smart Light Bulbs
The bulbs worked great with Alexa. Just tell her to turn them on or turn them off. Very easy to program my wife loves them. Just tell Alexa to turn them on or turn them off. Don’t even have to touch the switch. That’s just a start of my smart home.

Buen producto
El foco en cuestión es como la gran mayoría que existen en el mercado; lo resaltante de este producto es que, es de fácil instalación, su aplicación es muy fluida, se sincroniza súper rápido, la función con Alexa es genial, el brillo es regulable y el tono de la luz es muy amigable a la vista

Muy buena opción si no quieres tener MUCHAS lamparas
- Super facil de instalar y configurar - La App es super amigable - Se conecta al WiFi por lo que son economicas pero por lo mismo si llegas a tener muchas lamparas y enchufes puede poner mucha carga a la red - La integracion con Alexa es muy buena - Si se configuran bien es super lindo que las luces se prendan solas al atardecer y vayan subiendo de intensidad solas
