I have been using mine for a week now and love it. I keep my phone in my bag under my saddle and have had no issues. With the Bluetooth SC sensor and Bluetooth heart rate strap (both Wahoo) I get about seven to eight percent drop in battery per hour. Much better then the twenty to thirty percent I was seeing before. I am using the twist mount that came with the RFLKT+ on a Sram Edge mount so it sits out ahead of the bars.
