Scheduled battery replacement same day for a scheduled slot between 2-4pm and technician didn't arrive until 8:30pm. When he did arrive, it was super quick and effortless. Overall I do recommend if you're in a bind, but keep in mind that it may take considerably longer to arrive than you anticipate, so plan for that. I checked in with chat customer service 5 times to get ETAs. Although it was quick and easy to connect with a representative, it wasn't until the final check-in that I actually was able to get an actual ETA. Throughout the day I had no idea when he'd actually arrive, which made it hard to plan my day.
