The compact design ensures it doesn’t block any other outlets, and the voice control integration with Alexa and Google Assistant is a great bonus.Overall, this is a highly reliable and versatile smart plug that’s perfect for anyone looking to add smart functionality to their home.

Easy to use solution
I bought these to help setup a greenhouse or sorts in a room in the house to help manage the lights and fan and these have been perfect. All my succulents and cacti and orchids are exploding and flowering. It’s been a really easy way to manage everything so now I can go on vacation and not worry about it. They turn on for 12 hours and then turn off.Compatibility with Android has been easy. Pairing was quick. Following the step by step process in the app was simple and worked every time. Occasionally I do turn them off before the timer is up, and I can do it from anywhere in the house.The quality of the product is right where you would want it. Easy and simple, nothing to break. The manual on/off is a nice fat square button on the side to it. There’s a blue/orange light on the side to help you determine if it’s on or off, but then the light turns off so it won’t disturb your sleep if it’s in your bedroom.Manually turning these on/off either by the app or actually manually pressing them is quick and responsive. I’ve had a few occasions where they’ve done some funny things like not turn on when the timer said it was supposed to, but I chalk that up to up Internet and wifi setup being unreliable at times.I’ve purchased these plugs multiple times now as I’ve used them up and added more items to the growing network of houseplants and even though they’re no longer in the same room, they all go in sync. I always know when it’s 9am or 9pm because lights turn off on their own. It’s perfect!

So Easy
So far I’ve connected 2 LED light strips and misc other items with no problems. While I’ve found that initial set up takes a few minutes, the integrated app, complete with timers make these plugs super useful. Because I have 2 other KASA smart-plugs running through the app as well I really like the customizable icons that can be assigned to each device/plug. These plugs are well worth the purchase price.

WiFi plug – great value
Great socket controllers for the price. Setup is much easier than a few years ago when I bought my first Kasa and now these are very inexpensive, perhaps because they are the ‘latest and greatest’ new thing out. But the app makes it easy to group them, you can group them with Alexa for voice control, and it works great. There is no way to schedule things to come on and off however, so perhaps that is why these have become less expensive. Still a good buy for what they do IMO

La interfaz es bastante útil ya que te dice cuántos Watts se están consumiendo, así como el consumo total de energía en un lapso de tiempo determinado. Tiene varias opciones para programar los enchufes y no tenerlos prendidos todo el rato.

He pedido ya varias veces smart plugs y siempre viene uno defectuoso. Estos funcionaron bien los 4 y se ve que son de buena calidad. Lo que si he descubierto es que con los cambios de voltaje que a veces sufrimos se nos han descompuesto otros que hemos comprado así que estos los puse todos en lugares donde ya hay un protector de picos. Los use para programar las luces de navidad, otro para encender lámparas con focos grow light que uso para mis plantas y hasta ahorita no he tenido ningún problema. Lo único es que si me tarde en configurarlos, ya había hecho esto antes pero con estos necesitas usas su aplicación especial y luego me di cuenta que estaba seleccionando mal el tipo de contacto por que me fui por la imagen.

He usado y configurado dispositivos de otras marcas y siendo honesto creó que el setup de estos enchufes es de lo más intuitivo que hay, fáciles de encontrar e instalar, la app si bien es básica la verdad es que no hay mucho más que se le pueda pedir, tiene todas las funciones básicas y hasta el momento han estado funcionando sin problemas, relación calidad – precio esta excelente, los recomiendo
