Reviews
The hardest part of this was catching the right time to by as stock gets depleted quickly. The battery replacement went smoothly and, as promised, didn't require dealer configuration. I was concerned when there was a long (approx 1 hour) wait before the firmware upgrade finished. But the upgrade was successful and it was happily cutting again.
