Here's an update on the RFLKT for those that are curious. I've had the unit for about two weeks now and it's finally working without any glitches. I did have to replace the Garmin SC sensor, that belonged to my wife, with a new one. That fixed the problem with the erroneous max speed readings I was getting. I did have a slight problem getting the new SC sensor paired with the phone but after force killing the app and restarting it, the sensor paired instantly.

My big worry with the RFLKT was how much battery life it would drain from my iPhone 5c. Some of the guys I ride with use BlueTooth sensors and they really don't get a heck of a lot of battery life from their phones, even after optimizing them and killing all background apps. This coming weekend, I am doing a cross state ride and to prepare for it, some of the other guys doing it (who have never done one before) wanted to do two 60+ back to back rides over the weekend. The distances for the upcoming ride are 60, 80, and 70 miles. Over the weekend we did a 71 and 67 mile ride. We stayed within the speed of what the group is going to do on the actual ride, and including stopped time, the 71 mile ride took us right at 7 hours. The RFLKT was on the entire time, as was the GPS on the phone, and the battery life on the iPhone ended up with a 48% charge left. The 67 mile ride was a bit quicker and at the end the iPhone still had 58% battery life left. On my faster 45 mile daily rides, I'm only using up, on average, 12-15% of the battery.

This device is definitely a keeper. My only complaint is that the battery for the RFLKT is not a common CR2032 but a CR2450. Since these don't seem to be as common a battery type, they may end up sitting on a store shelf a lot longer and may not have a completely full charge when you buy a replacement battery. I purchased a three pack from Radio Shack and replaced the original battery and after 5 days of riding, it's down to 37%. According to Wahoo, the unit should run on a fresh battery for approximately one year. I don't know how they determined that but riding 3 hours a day, six days a week, I probably won't see that happen.
