Poor sensitivity. Will have to try something else. Maybe I'm lazy, but I have to get out of my easy chair to receive full functionality from cable box. The eye doesn't seem to be very consistent...it blinks and acts as if it's receiving a signal but quite often doesn't do anything.

Easily installed. Works very well.

Works for some devices don't work for some device! It didn't work for Scientific Atlanta Explorer 8300HDC / Comcast xfinity DVRs both models. Check for IR frequency before purchasing it, several comments in AV Forum site for the reason it don't work. Smarthome shouldn't decisive customer but should clearly state the IR frequency range as well as known device that wan't work at least that don't work such as U-verse, comcast, DirectTV - All major US Cable DVRs - let me say, I only confirm it don't work for Comcast The 50' extension cable Item# 8186. Lot is written that it don't work with Smarthome IR. It does work but one has to push male end of the cable in IR repeater box, the other end bit hard since the plastic comes in a way for perfect connection. Some people peel some plastic off, I just pushed hard, it works. I am able to automate entire activity for my netflix Vizio TV, Pioneer AV receiver and Sony Blu Ray, no success when it comes to xfinity DVR. I may have to look for Xantech IR repeater for xfinity DVR.

Every well discribed product made it simple for me to order

I did not get a chance to test the product. When design for entertainment center was completed, I determined that the repeater system was not needed. Product was returned unopened. Rating is based on speed of delivery and ease of ordering.

Easy to hookup. But suffers from wide field of view. Great straight on.

Did not work with Comcast DVR box (CISCO)

Easy setup, good instructions, took less than two minutes to setup. Unfortunately it didn't work with my cable box which is a Cisco box from Comcast. I tried moving the IR reciever to a couple of different spots but couldn't get it to work. I returned the product and Smarthome paid for the return postage.

Works well right out of the box, easy set up. Good Value. My only comment: The power adapter / plug is one of the older, heavier types that get warm - so I suspect it has a higher vampire power draw than newer, light weight versions of the same thing - but I haven't plugged it into a Kill-a-watt yet to test it.

Works great with TiVo Series 3 after a couple of tweaks. First, a few peculiar details about ordering and price. I ordered it from the Smarthome site, which has a Pay With Amazon payment option, that I chose, since it was the quickest and easiest. It was delivered in a few days as promised and I am as happy with Smarthome's service as I am with Amazon's. But here are the anomalies: The Smarthome price on its site was $40 I'm rounding all prices for simplicity, but when I paid for it the price was shown as $30. It was right around Xmas, when many prices go crazy, so I assume it was a short term price special. BUT as of today 12/30/2012, the price on the Smarthome site is still shown as $40, the Amazon price, as sold BY Amazon, is $49, and the Smarthome price as shown in two different places on the Amazon site is $40 AND $49! I'm sure those prices will change, and there is no way I know of I will be able to prove it in the future, but I've confirmed numerous times what I am writing is ABSOLUTELY CORRECT!! I don't understand the pricing goofiness. As to the repeater device: When I first installed it, it worked intermittently and would freeze up after a short time, i.e., stop working at all. The Repeater can control 8 separate boxes, but I am only using it with one, the TiVo I mentioned above, but I am not using it on a hidden TiVo in a cabinet. My TiVo box is in a low open shelf TV table at the wall past the foot of our bed, and the line-of-sight from the remote to the TiVo is obstructed by the bed clothes and the end of our mattress, especially when elevated by a pillow or our feet, so we had to raise the remote about 3-4 feet in the air and point it downward to make it work, which was frustrating my wife, to say the least. I figured a high mounted IR repeater receiver would do the trick, and it eventually did, with the tweaks. The instructions say to find the IR Infrared eye on the component you want to control, saying to shine a flashlight into the front of the component and describing it as a small red disk. I couldn't see a small red disk so I contacted TiVo support by a chat and was quickly told the IR eye is at the right of the front panel window. When I looked with a flashlight I couldn't find an eye, but there is a one-half inch square. Turns out I had the small emitter in the wrong place, which worked, but not very well, but when I relocated the emitter over the eye/square, I encountered the same intermittent operation/freeze-up problem. I eventually unscientifically theorized the IR beam from the remote control was confusing the TiVo box because it was causing the IR signal to arrive at the box through the repeater emitter AND from the remote directly, the two signals getting there a microsecond apart. I have no idea if my theory is correct, but I hung a folded piece of cardboard over the front of the TiVo, covering the square IR eye so the IR signal from the remote can't reach it, and all I can say IT WORKS!! So
