Who a chic, comfortable and robust unit for max. 4 units examined is hereby well served, the price-performance ratio is super. The 300i has as opposed to 300 glossy piano finish, are otherwise functionally identical. This FB is ideal for (eg cable / satellite receiver, AV receiver, BD / DVD players) to control a TV plus biszu 3 additional devices. There are enough to pretty much map keys, all functions of the original FBs, and you could very kofortabel program on the PC. Almost all devices are already available in the Harmony database, so one gets a good basic configuration through the device selection. Then you can edit each of the 4 devices and change the button assignment to device functions individually. You can also teach commands from the original FBs, which was not necessary but for me. The "Watch TV" Power button is used for all TV look necessary equipment (eg TV, cable box and AV receiver) switch on simultaneously and switch off again. However, one can not program expanded macros, for example, that then also the correct input is selected at the AV receiver, and the sound settings for TV can be selected. The volume plus / minus and Mute keys to (other device ev.) May apply to any device prgrammieren, on which they act, for example, always on the TV or the AV receiver. There is also a TV input button, with which you can always switch between different input for the TV. There are also 4 keys which are intended to store favorite stations (so you can, for example a multi-digit Program no. Then a button select).
The FB is battery powered (2 x AA Duracell attached), is very good in the hand, looks classy (apart Allerding light dirt on the piano lacquer surface) and makes a high quality impression. The buttons are easy to operate and does not bounce. However, they are not illuminated, except the 4 product code keys (so you can see when pressed, which is the 4 devices selected). There is also no display, as in the more expensive Harmony models. It comes with the USB cable for programming on PC or Mac.
Conclusion: if max. Wants to control 4 devices, this does not require any complex macros, no button illumination and no display needs, and the relatively simple and convenient programming on the PC / Mac does not shrink, which is the Harmony 300 (i) fully recommended.
