Cheap and works - Poor IR Range

Cheap and works  2035 battery cells and remote IR sensor (really helps as range poor}

Works well. I had to place one IR transmitter dinky link on each of the two IR windows on the projectors for some reason. Some times these units work well with the dinky link IR transmitter hanging close to an IR window on the device and won't work stuck to the window.

it did what I expected it to do.

Only one, thing the IR remote works but not very sensitive. Some times you need to position it just in from of the cable box to be able to catch the signal.

Narrow IR beam. Would only work when pointed directly at the Roku, and then only when it was within 6 feet. Many times I had to get up and stand next to the device with the remote. Kind of defies the whole purpose of a remote, doesn't it?

works,its cheap,working range is more like 800 feet  any more and ure going to have a signal strength like dial up

I bought this item because I needed something that would split off the audio stream from an HDMI cable. It was the cheapest one I was able to find. I assume most people would be buying it for the same reason. The device works as wanted. But, there are a few rough spots. The remote control connection to the unit seems to be spotty; ie one usually has to repeatedly hit the remote button for the desired port selection multiple times to get the unit to respond, as well as appearing to have a small range (probably around 12ft) to work. Changing ports also takes a few seconds to complete. But, all does function as intended. Considering alot of similar products are in the $100+ range, probably a good deal. I rated this product under the assumption 1 star being bad and 3 stars = average

I purchased this remote in hopes of using my iphone to control my outdoor TV.
the wireless connection was very glitchy (although my outdoor TV has wireless and has no issues)
and, the remote has no IR signal, so if you want to control a TV that is not next to the components, it won't work.
for some applications this may be OK, but it did not work for mine.
I purchased a URC RF-20 and for half the price it works very well.

Works well but the remote is infrared so you have to have line of sight for it to work. Really? Talk about a crappy design. The remote should have been RF. The reason I bought this unit was 50% for the remote but having to have line-of-sight is ...... annoying.

Well when I saw the price I should have known it wouldn't be very good. The night vision does work and I can see about 30 yards. The Image is in black and white not green which isn't a big deal but it didn't state that anywhere. The image is extremely small and requires constant adjustment and you can't see anything without the IR on.

I bought two sets of these and they will give you an image through them. The issue I had was that they would not send the ir signal through them like the manual says. I tried both sets of units. I even connected it through a 6foot cable. Both sets would not pass ir through in either direction. There is no phone number for support that I have seen so I result to writing this review. One of my projectors also has fine lines going through it. It is not terribly bad, but I can see it. These units are used in a church.

Has good range (30 ft through 4 walls). Works with Raspberry Pi (both OpenELEC as well as other Linux distros for RPi).
Good value for the money.

Works perfectly to extend IR signal of DirecTV receiver in hidden cabinet. I was NOT about to use that new POS "peanut" remote (RC73) that the new receivers require to run RF.  I recently got a new receiver and found out that the far superior RC66RX would not work in RF mode. This doesn't make it RF, but it gets the job done as the sensor on this thing is pretty sensitive, which is great.

Works OK if you don't need to have any distance between items. Signal not strong enough for 75+ feet. Image grainy on second TV and drops out on the third. Had to order a different unit that boosts the signal.

Seems to work ok. Didnt realize it uses IR instead of the wireless interface like an Xbox controller. So if your console is in a weird spot you might have some problems using it.

Doesn't have great range but thats only because its tiny. It works, even with Linux, and I've paired plenty of things to it that work fine. Generally has signal degradation through walls or at a distance of about 4 meters.

I don't know about the remote that comes with the package, because I am using a Harmony 720 with it.  I have really good angle able to just point in general direction of IR receiver and it picks it up!  Works with Windows Media Center and Also was able to get it running in Linux with some tweaking.

Works okay for the price, buy range is very poor and so is the audio quality.
