Purchased 3 units. Was able to program remotes to the desired receiver with no crossover interference to wrong receivers. Also no crossover interference with other receivers already in use. Very good. Also if you like just place a small piece of black electrical tape over the photo sensor eye they will now work as a daylight timer! Overall these remote timers enabled my outdoor landscape lighting and water features total independent control! Never liked centralizing everything to my phone or alexa. These are nice well constructed straight forward units that look good in black.Super easy to use. I bought it for my Christmas lights so it works perfectly because of the dusk/dawn setting. Got a little wonky sometimes because my plug ins are on my front porch lights so they didn't turn on sometimes when the light was on. But otherwise works great for Christmas lights.Good product.What I like about it is that you can use one control for how many as you want.Very easy to use and setup. Nicely built and sealed. Used for exterior Christmas lights.I set mine to 6 hours. It comes on at sunset, sunset is front of my home. No problems rain or snow.Works greatEasy to setI have a small house and used the same extension for both outdoor and indoor Christmas lights. It took me a second to get the remote programmed but now LOVE this set up!! I can set how many hours and make sure it's on for when company comes. Love this product!!!This product is doing exactly what I want it to do. Bought it to turn on and off my Christmas lights. I use the dusk feature and then run for 8 hours. Works perfect because as dusk changes it doesn't turn them on when it is to light out.Figuring out the set button to pair a remote with 1 of the plugs was NOT described good at all but, once figured out it works great. No more running out twice a night to turn on/off the christmas lights. Very happy with the purchase. Remote as well as the timer both work wellWorks really well, just make sure you sync your remote to your wall plug in or it won’t work.Once I did that everything has been working great.Would definitely recommend, it save me having to run out into the cold to turn off the Christmas lights.Working well, easy to set, remote is very useful. Its nice for my christmas lights
