Success. Spectacularly happy with the unit. Works flawlessly and solves all the problems I was hoping it would solve. All components in my system now respond to the remote thanks to the IR blasters. Before this, I frequently needed to re-try the remote commands, or needed to hold the remote at a special angle and stretch to make sure all its signals were recieved. Now I can just be a lazy ass, barely lift the remote, and vaguely point it in the general direction of the TV, and everything just works.

The receiver puck is very unobtrusive. It's smaller than the pictures made it seem. The blasters are tiny and stick nicely to the components with the double-stick tape, their wires are thin and easy to hide/tuck. The 12-volt wall-wart adapter is one of the somewhat-more-convenient type, designed to take up less space on the power strip.

An unexpected pleasant surprise: Both the reciever, and all the blasters, have bright visible-red LED blink indicators which flash when there is IR traffic. This is exceptionally useful when setting up and testing the unit, you can see instantly if it's getting a signal from your remote. In my case, I had managed to run the wires for two of the blasters but forgot to plug them in. So I was able to see instantly what I had done wrong because two of the blasters didn't blink.

If I could change one thing about the unit, it would be this: The wires running to the blasters and the receiver have a little white stripe so that you can know the wiring polarity if you have to cut the connectors and wire by hand. This means that, for the short distance that the wires must run across the face of a component to reach its IR sensor, the wires are more visible than they otherwise would be running across the shiny black A/V components. For example, the IR blaster stuck to the IR sensor on the front of my TV, I can see the little wire running to it a bit more clearly than I would have if the wire were just pure black. Now, this thing's purpose was to actually *hide* the components, which I'm not doing, so that's kind of my fault.

Oh hey, I just realized I could hit the white stripe with a sharpie and solve that problem. Shall do that next, and then it will be perfect.

Thanks, everyone, for the recommendations!
