I just got a RFLKT+. Received it last night in time to go riding.

It works well. After looking at the iPhone display, I have to say I do miss that but the LCD display on the RFLKT+ is pretty much equivalent to anything out there with that sort of display. It's easy to use, the button use is intuitive with the default settings with Cyclemeter. What is notable, however, is the battery usages is really much lower - less than half. If I had my iPhone display up all the way, it would drop about 40-45% in an hour or so of riding. If I turned it down half way, then about 30%. With the RFLKT+ on and the iPhone display off, it's about 10% (and that included a phone call). So based on that, albeit just a single ride, I'd have to say that with the RFLKT+, the iPhone's battery (if fully charged) is probably good for 7 hours or better.

Cyclemeter lets you design your own screens for the RFLKT+ and lets you customize the functions assigned to each button.
