Herfair IR Repeater Transmitter Kit Up to 15FT Signal Range - Infrared Remote Control Extender Universal IR Blaster Emitter with Receiver for Cable Box/STB/Amplifier (USB Powered, 10FT)

Cheap, easy to install, and works as expected.

My elderly mother has limited range of motion in her arms and was struggling to get the remote and TV to communicate without a major struggle. I set this up in under 2 minutes and it worked immediately. In her situation we mounted the receiver portion above her tv and there is no lag and the tv responds to her remote with little effort from her. She was so happy with this solution and so was I. Amazing price for a great solution to a very frustrating problem. I can’t speak as to how well it would work on a very large room but it does amazingly well in her averaged sized living room. Cord length was more than adequate on her 65 inch tv.

Does what it's supposed to do! Not perfect, but makes using remotes for various purposes in my camper van much easier without having to point directly at devices across the van, or from the just the right angles. But I really wish it came with two IR receivers, it's got more sender than I need, but only one receiver. I'm not seeing where to buy more receivers, even though it's got ports for more of them. REALLY should come with at least two! Wish I could give it 3.5 stars, but I'll be generous and give 4 because at least it has lot's of IR sender and receiver ports. Serious bit of kit for what it does compared to most devices like this which are simpler and less powerful.

Truly plug and play addition to my home TV system.I have a large screen and a long soundbar. The soundbar blocks the TV ir sensor. The fix was easy handy works well and affordable.

Inexpensive but just works with no hesitation.

I wanted to automate my electric fireplace with Hubitat Elevation but had no place to put an IR blaster (BroadLink RM4mini) in line of site. I was looking for repeater with a small transmitter so I gave this a try. It works perfectly. The transmitter if very small and the wire is not bulky, so I was able to run the wire from behind the fireplace to the front and attach it with the provided adhesive. No more hunting for the remote, simply say "turn on fireplace". Who's lazy? :)

works as expected except there is a terribly long lag in input response so pressing the buttons quickly will result in some annoying loss of input

This ir repeater works well. It doesn't have the most tacky tape to hold onto the unit though that can be good since I have already had to move some of the emitters around. Pretty much plug and play. Killer value and works with all remote controls I have. Just make sure you are able to find the IR sensor on your target unit.
