I really have no complaints about any of the TP-Link Kasa products. I now have 2 tanks with their lights on single Kasa Smart Plugs and my 55 gal high-tech with the Kasa Strip; that's 4 lights, a backlight, filter, CO2, powerhead, doser, and UV connected on Kasa ecosystem.
They are all controlled on one single app that has a bunch of functionality and integration. You can add multiple on/off times, disable each scheduled time individually, set the schedule to sunrise and sunset times, and use away mode to set a random schedule, just to name a few features. Away mode works well if you do not want to have your UV running continuously (try to lengthen the bulb life). You can create groups for turning things off all at the same time (such as lights).
I really haven't had any issues with them for the past year or so that I've had them. One odd situation I found myself in was waking up one morning to my filter being off on my 55 gal. Turns out it was one of the Google Home routines that had turned it off when I told Google "It's movie time" (Telling Google "It's movie time" turns off the aquarium lights so that I can watch a movie in the dark). I had recently changed the outlet where my filter goes on the power strip to where the backlight used to be plugged in. This caused the filter to turn off instead of the backlight. Fixing the routine quickly fixed that.
All-in-all I have no negative things to say about the Kasa products (I love my TP-link router and powerline adapters as well). I have some experience with other off-brand smart products and it always seems to go back to the old saying "you get what you pay for". The apps aren't well organized and reliability is spotty.
I would definitely recommend to anybody that is curious.
