In Orlando, FL. I used this service for a dead car battery. The car starter wouldn't turn, the battery was three years old, had corrosion coming out of both posts, so I knew it was dead. I made an appointment online. I chose a battery from many options offered after I put in my car's info. They asked for address, phone, and email. They gave me a price for delivery and install. I paid and got confirmation instantly. By text and email (It was a Friday evening when I made the appointment for Saturday morning). I received a text and email on Saturday morning when the tech was on the way with the car battery (about 1 and 1/2 before my reserved time window). The tech arrived 30 minutes before the reserved time window but I was able to track him with the link in the text so when I walked out to my car he was just approaching my place. Took him about 10 minutes to swap out the battery out of my car. Very fast and clean. Great service!
