The Good: The Logitech Harmony 670 is a throwback to the comfortable peanut-shape design of old, with DVR-friendly buttons placed in the center. It retains the same great features and functionality that the Harmony line is known for, such as activity or device-based command, PC\/Mac programmability, and a contextual LCD screen. The Bad: The 670 isn't as sleek or as stylish as the more-recent "flat" Harmony models. Moreover, it lacks the rechargeable battery\/cradle and color LCD found on higher-end Harmony models. Even with an upgrade in place, the Web-based programming can still intimidate nontechie users. And the remote's silver finish scuffs pretty easily. The Bottom Line: The Logitech Harmony 670 may not be the coolest-looking universal remote, but it's one of the easiest to use, especially for DVR users. Editor's Note (February 19, 2009): The rating on this product has been changed due to competitive changes in the marketplace. Readers interested in this product should compare it to the more recent Logitech Harmony One.\n\n\n\nMost of the Logitech Harmony universal remotes we've seen in 2006 have sported a flat, wedge-shaped design. They look slick, but apparently quite a few users are still pining for the textured feel of Logitech's older, peanut-shape clickers. Logitech has answered with the Harmony 670, a $150 model that utilizes the "classic" rounded design of past models, paired with some notable design tweaks and--of course--the latest Harmony software. \n\nFrom a distance, the Logitech Harmony 670 could be confused with earlier 600-series Harmony models. It measures in at 8 inches long, 2 to 2.5 inches wide and 1.5 inches deep. While we prefer the slim and sleek design of the 500-series Harmony models, the peanut style--very reminiscent of the TiVo remotes--is a bit more comfortable in hand, with finger grooves on the back of the remote. The silver-and-black motif of the remote allows it to blend with most home-theater devices, but the silver finish scuffed quicker than any Harmony remote we've seen before. \n\nThe Logitech Harmony 670 crams an astounding number of buttons onto its frame, including a complete numeric keypad, full video-transport controls (play, record, rewind, pause, and so forth), a four-way directional pad, and hotkeys for DVR use as well as quick jumps to the most-used activities (see below). The functional highlight of the Harmony remote series, however, is the LCD screen. Flanked by programmable keys that you can label differently on separate pages, it allows the Harmony to emulate even the even the most esoteric buttons as well as engage activities and macros. While the LCD display works well most of the time, we prefer the one used on the 500 series. With smaller text and fewer buttons by the LCD--four to the 670's six--you're able to read the functions on the screen much more easily. (The 670's default mode actually uses only four of its six contextual buttons, with the top two reserved for the device or activity name, but you can easily toggle the preferences to use all six.) While we were testing the remote, we ran into a few instances where text from the upper-left corner crowded in on text from the upper right, with important text being obscured--the 2 in Input Component 2, for example. Besides the tricky LCD and a difficult-to-find backlight button, the layout for the 670 is pretty good. The buttons on the 670 are placed well, and all consist of the same responsive, hard plastic, which works much better than the mix of rubbery and nontactile metal buttons on the 500-series remotes.
