Good deal on a great set of 4 smart plugs!

Tony JWDecember 11, 2025

I have used them for just over a month now and I am very pleased with these plugs. The set of 4 is a great value for good quality. They seem to be durable and well made with clear light display to indicate plug status. Easy to set up, and use. Works with the Kasa app that I use for my outdoor plugs but also works with my Alexa and Google home set up. These work perfectly as automation control and timers for our Christmas lights. I have them set up on the 2.5g part of my network which is the same as my other smart plugs, outdoor cameras. Read more

Easy to use

JCDecember 6, 2025

This is my second time purchasing these kasa smart plugs. They are very easy to use and install. The app is also very easy to use, understand and create schedules. I can also turn them on and off from the app. I currently am using them for all my christmas lights and trees and they work great. They stay connected although a couple of times they have gotten disconnected. But I feel that is normal and doesn't happen often. They also work great for saving money because I dont forget to turn things off now , and if I do I can turn it off from my phone. Read more

The Smart Plug That's Actually Smart About Setup

Vine & DandySeptember 24, 2025

I've used a lot of smart home gadgets, and often the "easy setup" promised on the box turns into a frustrating session of troubleshooting. The Kasa Smart Plug HS103P4, however, is the rare exception. It lives up to its name by being incredibly easy to get up and running, especially with the ecosystems that matter most to me: SmartThings and Alexa. The initial setup with the Kasa app itself was a breeze. I had all four plugs connected to my Wi-Fi in a matter of minutes. The app guides you through the process step-by-step, and it just worked flawlessly, with no unexpected connection drops or firmware issues. But the real magic happened when I linked it to my smart home hubs. For Alexa, it was as simple as enabling the Kasa skill and letting it discover the new devices. Within seconds, I was using voice commands to turn my lights and appliances on and off. The response time is instantaneous, and the reliability has been perfect—Alexa has never failed to control a Kasa plug. Integrating with SmartThings was equally painless. The connection process was straightforward, and the plugs appeared in my SmartThings app with all the functionality I needed. This has allowed me to incorporate them into more complex automations, like having a lamp turn on automatically when I open the door. In a market full of smart plugs that can be a headache to install, the Kasa HS103P4 stands out as a dependable, user-friendly choice. If you're looking for a plug that plays well with Alexa or SmartThings and won't leave you frustrated, this is the one to get. Read more

These work great, are easy to setup, easy to program and perform perfectly all the time.

If you need a timer for whatever reason, these are the best. I have so many of these and I use them all over our home for turning lights on and off. Well of course that's what they're for, right? Ever set up a Christmas tree, get it plugged in and then when it was bedtime you struggled to reach the outlet to unplug those lights? I know I have. Sure, you can buy one of those step on switches that you plug your light strings into. But these make it so much easier to control and setup. There's a small learning curve to get it loaded onto your home internet, but once you've done one the rest are a breeze. Yup, your internet. No it's not going to slow it down and no it's not going to create issues with other wifi connected devices. In my home, I use not only these outlets, but I also use the wall switches, both single and three way switches. Also use the outlets that are meant for being outside in the weather from this same company. And they all work perfectly. Just to give you an idea I have at one time, mainly during the Holidays, I have at least 15 of these outlets around inside my home. Add into that 4 wall switches and another 4 outdoor weather resistant plugs. Take all those along with laptops, phones, speakers, tv's, tablets and I forget what else and I have zero issues with my 500GB internet speed. As for the plugs, they connect to your internet quickly, easily, install the app on your phone, laptop, tablet whatever to set them up and your good to go. Program them anyway you need, on at dusk, off at dawn, on or off at any time of day or night any number of days you want, and they work flawlessly. The outlets I have outside work no matter the weather, they're just as durable as you need. We have one that's located 60-70 feet outside, from our home and we can easily control it from inside our house. Did you leave the house and leave something plugged into a timer you didn't really want to have come on when you're not home? Just go into the app and turn it off, from wherever you are. Honestly I can't say enough good things about these plugs. The only scary part is when you have several of them scheduled to turn on at one certain time, like say dusk and all of sudden you're walking around and click, click, click, lights are coming on everywhere. Oh, and if your internet goes down, you won't have control of them through the app. But you can walk up to any plug, push the button on the side and it'll turn on or push the toggle on the light switch it'll still turn on. And they don't lose their programing, if the internet's not available, they will still turn on and off just as though they were connected to the internet. Then when your internet connection returns, they automatically reconnect, just like any other device you might have. Read more

easy to install, works as advertised!

DNADecember 13, 2025

The four pack of plugs arrived quickly & the directions were clear. Ease of use was obviously taken seriously because I dl'd the app & added each device super quick. Finally, a smart device that does not take drama to install. Read more

One more easy way to make your life simpler.

Erin S.December 27, 2025

I love these smart plugs to use in all areas of our home... But they have been especially nice to use this holiday season. I have not had any issues with them not responding. And I love that I can use them with our Echo devices and control them when we are aren't at home. I'll probably end up buying more of these and use them in other places in our house. They're very easy to set up and seamless to use. Read more
