If you've already used a Logitech Harmony remote control, you might find the simplified approach of the 200 restrictive. However, it's just the ticket if some of the people using it have a slightly technophobic bent.
Pressing on of the white device selector buttons re-configures switches the black buttons below to work with your three devices of choice. How well-mapped these are is in part up to you - Logitech doesn't put a foot wrong here. It is a shame that there's no way to tell which device is currently selected. With no display and no backlight to the buttons, the only way to be sure is to press the white button again - which we can envisage some less tech-savvy folk doing.
Of course, most people settle into the habit of only really controlling their TV-watching experience through one device - most probably a Sky box or PVR if you have one. So, you'll be able to keep the same device selected for the most part.
This approach is rather different from Logitech's more advanced devices, which let you splice and dice the functions of the control buttons between your devices depending on what activity you're undertaking. In short, while others are driven by macros, the Harmony 200 is driven by devices. It's a less adventurous style, but ultimately more intuitive for many people.
Its 3-device limit is severely limiting, though. The slightly more expensive Harmony 300 opens-up support for four devices and offers a few more buttons, without charging many more pounds for the privilege. Now that the Harmony range has filled-out, there really is a device for just about everyone within its walls.
If your setup is particularly rudimentary, and is used by those without a degree in geek, the Logitech Harmony 200 is an excellent choice. It feels sturdier than most of its rivals, doesn't cost the earth and benefits from the fantastic Harmony database. We imagine many of you would benefit from the extra device added by the Harmony 300 and 300i (the glossy alternative), but then the 200 is arguably even simpler to use.
The Logitech Harmony 200 is a deliberately limited device. It can only replace three remotes, but, if that's all you need, it's a real star. It's highly affordable, much easier to setup than most universal remotes and feels just as well-made as its more expensive counterparts. If your living room co-habitees can't hack an advanced universal remote, this is a great solution.
