Every 20 mins or so my recordings stop and re-start. I didn’t know the device even had the loop feature ! The first card I used was the SanDisk, with that the machine just stopped recording when it felt like it. This is the second recommended SD I am using. I’ve just ordered the recommended Samsung card so maybe third time lucky but christ almighty they ain’t cheap ! What memory card do my fellow users use that works for them ? If this card fails it’s going back to the retailer as faulty and I’ll be shopping for something different that starts with go. I’m so frustrated and disappointed.
