Having never used a ride-sharing service before, I hesistantly installed Lyft and handed over my payment information.
After the first ride, I didn't look back. I used their services maybe 10 times in 3 days in order to get around the city. Waits were never very long (we got rides at many different times of day, morning, mid-day, late night) and all of the drivers I had were friendly.
My experiences were all pleasant and the fares were reasonable. I can't speak to the quality of the Uber experience, but it seems many of the Lyft drivers were not too keen on the company.
