Great way to control TV and radio in one room from an easy chair in another room!
I help a 96 year old blinded vet with tech support -- and as his health worsens, needed to make his TV, his radio, and the audio switch that selects what audio should go into his hearing aids via Bluetooth work from his easy chair in his living room. All the equipment is in his bedroom. This IR repeater system installed quickly and easily and works perfectly. Now he can summon ball games, news, or whatever he wants without fear of getting up and falling down. A perfect solution!

Magic!!!
I am no tech expert but these little guys are magic! We had just put in a wall of built-ins and desperately wanted to hide our cable box behind a cabinet, but with it being infrared this would not work without these little repeaters! First off I just have to say that the Sewell customer service is off the charts. You actually get to speak to a real person right away, no annoying menu after menu trying to get help. They helped us so much when we hit a couple snags. Here are a couple things that I figured out that I hope will help others. First you can hide both of these little discs, they both come with tiny little eyes that can attach to your tv and cable box or whatever you are trying to use them for, and they are nearly invisible. Second, don’t get nervous when you plug them into the power outlet and the lights don’t come on, this is ok and they aren’t supposed to stay on, they kind of blink here and there, and only when you use your remote. Third, we have an Altice One cable box (not the mini, just a regular cable box) and it was impossible to find the eye to attach the emitter’s eye (Side note: we had to put the emitter disc on top of the cable box because we couldn’t fit the emitter disc pointing in front of cable box. The directions give you both options though and you can basically put it anywhere as long as the eyes attach). The phone trick did not work on this particular cable box. But after trying about a dozen different spots on the front of the box we finally got it to work by putting the eye right on where the digital clock numbers are. I put it basically right on top of the colon (:). Cable vision was no help with this so I hope this can save others from our frustration. After we found the eye everything came together and worked perfectly! No more do we need to keep the cabinet open to change channels… it’s a miracle!!! Hope these little guys work forever.

Good product, expensive price, poor adhesive
Premium packaging for a premium device. Useful for IR remote signal delivery with extra functions on the side. Price though is luxury for it’s use. Used this for a Logitech Harmony hub control of an non-smart electric fireplace. Setup is a breeze but only if you’re tech savvy. Highly recommend to watch the YouTube video for information on all it’s application. There a many other cheaper devices similar to this available on Amazon that I could have used for the same application. If you have a need for multiple control within the same vicinity of other devices, this may be more useful for you. However, if you plan on utilizing an IR repeater/extender for only a single device and would like to save some money, don’t buy this one. This device works quite well though. Have had no issues achieving the effect needed. Only four stars due to the poor adhesive on the emitter attachment. As stated earlier, I used this on an electric fireplace with a glass surface. I used the attachable emitter to the front glass sensor where the IR receiver was located on the fireplace. After only one day, the emitter attachment fell off even though I made sure the glass was thoroughly cleaned prior to adhering it. Otherwise a good product.

Denon avr ir remote port works great with sewell products
I bought a new entertainment center with glass doors and wasn't getting good signal range with the door closed. Plus i couldnt get a good of line site, since this cabinet was shorter than the orginal, and the location for my avr was further to the left than before and now my line of sight to the receiver was blocked from other parts of the room due to high couch back.
I tried a couple different cheap $10 devices that used stick on transmitters/receiver buttons but they were clumsy and didn't provide me a total solution for my room layout.
Works fantastic with a denon x1800 receiver (and many other models). It works directly with the denon's ir remote port in the back of the avr port. The solution is actually quite simple.
Plug a stereo 3.5 mm male to male plug in the denon ir port in the back of the avr and and the other end to the orange emitter box(puck). The pics are about the size of an oreo double stuff cookie Tuck the orange box/puck away whereever and plug the power in. The box doesn't need to seen or be pointed towards anything. It's location is only limited by the length of your stereo cable and access to AC power
Put the blue box puck anywhere in the room where you have general line of sight to it from where you will be using your remote, and plug power in. In my case, its sitting on top of one of my tower speakers. From there it clears the back of the couch and can see from the family room, eat-in kitchen area, and the kitchen beyond.
Done.
I didn't need or use any of the included emitter or transmitter cables, though if you dont have a denon, or other brand avr with an ir port to plug into , or also want to hide the blue puck ( in which case attach the included sensor cable), you'll need them. But for denon users with an ir port, you just use the two pucks and their usb power adapters. Simple.
