I have one. My view is that the BT transfer is too slow for every reading. I only use the Accu-chek for libre confirmation, so only need to upload to mySugr as and when. I don't think I could use it full yime.
I thought it was pretty neat at first. Then I started using Libre. Initially I was using Glimp and it it worked well for importing prick tests for calibration. However, I'm now using xDrip+ with a MiaoMiao and it is quicker to enter the Accu chek readings manually for calibration than to transfer them.
I sort of feel that it is a too little too late from Roche with the rise of flash glucose monitoring and continuous monitoring.
