    This worked perfectly for my Christmas tree lights and star setup. Wanted a timer and control function without having to reach for the outlet. KASA items are super easy to connect to your WIFI/Phone, took less than 2 minutes to get everything and working. Great value as well, quality build.

    I honestly love this extension cord because it works through Wi-Fi and I can control my devices even if I am not in the house. There is a timer I can set it up. It works with Alexa. The insulation was pretty simple. The size and the shape are good and it actually looks nice. The cord is not very long but for what I needed works pretty good. It’s easy to use easy install and it’s worth it of the money.

    5.0 out of 5 stars Kasa KP303: Savvy Powerplay for the Discerning Techie
    Reviewed in the United States on January 13, 2024
    As a hardware hacker with a penchant for home automation, Kasa's KP303 piqued my curiosity. Three individually controllable smart outlets, 2.4GHz Wi-Fi connectivity, and ETL-certified surge protection – all in a compact, user-friendly package? Sign me up.

    Initial setup was a breeze, the Kasa app guiding me through a painless Wi-Fi handshake. Connectivity remains rock-solid, even on the fringes of my router's reach, thanks to its sensitive 5dBi antennas. Individual outlet control is a boon, letting me power-cycle finicky devices or automate elaborate "movie night" routines through the app's intuitive timer and scheduling features.

    Speaking of the app, it's a geek's playground. Granular power monitoring lets me track individual outlet consumption, which is a boon for optimizing energy use. The local API access, a hidden gem, opens doors for custom Raspberry Pi integrations and voice control beyond Alexa and Google Assistant.

    However, no tech gem is flawless. The lack of 5GHz Wi-Fi support might irk bandwidth-hungry users, and the app's versatile automation options could benefit from more advanced logic like geofencing or IFTTT compatibility.

    The Kasa KP303 is a potent blend of user-friendly convenience and techie delight. Its robust connectivity, individual outlet control, and hidden API access make it a steal for the price. While it won't replace my Frankenstein's monster of custom Pi-powered relays, it's earned a permanent spot on my workbench – and a solid recommendation for tech-savvy tinkerers seeking a smart power upgrade.

    4.0 out of 5 stars Works well ... nearly all of the time
    Reviewed in the United States on September 20, 2023
    This smart power strip continues to do what it's advertised to do ... 99.9% of the time. That 0.1% is the problem, but I'll get to that.

    It worked out of the box using the instructions provided. I downloaded the Kasa Smart app onto my phone, and after setup I was able to name and control the power strip's three outlets (I got the version with three outlets) independently, or combine two or all of them together into a group and control them at the same time. I can also control them with Google Home. It's advertised as also being compatible with Alexa, but I don't have anything with Alexa, so I can't test that firsthand.

    Each outlet also has a toggle button that allows the user to switch that outlet on or off manually, and each button has an LED that shows whether the outlet is currently supplying power to whatever's plugged into it. This is a bigger deal than one might think at first. Imagine a desk lamp with a chain that can be pulled to turn it on or off, but you can't tell by just looking at it whether that pull-chain switch is on or off. Now imagine that you plug it into this power strip and it doesn't light up. Where's the problem – is the light bulb burned out? Is the lamp turned off? Is the power strip's outlet off? Well, I can eliminate the third question by just looking at this power strip and making sure that the outlet is on, so one pull of the lamp's chain will tell me whether the light bulb is burned out or not.

    The thing is, occasionally the power strip will just suddenly stop responding to the network. I don't know what causes this, but it will suddenly and silently disconnect; its power light and connection light will say that it's powered and connected to wi-fi, but the app says it can't contact the device. I can still manually toggle the outlets on and off with the buttons, but I can't control it with the app, or Google Home, etc. I can unplug the device and plug it back in, resetting it, and things work again. But I never know when it's going to glitch again, and that unreliability is what gives this device four stars instead of five for me. It doesn't happen every day – it's been weeks since the last time it happened, in fact – but not knowing what caused it or when it's going to happen again adds just enough uncertainty that I can't quite trust it. I'm not going to plug anything into it that might be disastrous if it couldn't be controlled.

    Very well designed other than that shadow of unreliability.

    So far so good - really easy set up and working as I hoped. I used this to replace a bulky outlet extender and timer. I really appreciate the design.

    I have a total of 22 Kasa outlets throughout my house, nine of which are these power strips. They are incredibly easy to set up and the ability to create independent schedules for each outlet is a game-changer. I have a variety of different lights and decorations plugged into the outlets and I love that I can either have them all turn on/off on schedules or I can manually turn them on/off with the easy-to-use app. The added bonus of the USB ports is just the cherry on top. Using Kasa products to plug all of my holiday decorations into means all of my holiday cheer is scheduled and I don’t have to run around the house turning things on and off. Like it said, it’s a game-changer.
