I used it once when my battery died, I didn't realize it was just the battery at that moment. It was fine. I'd use them again. But one thing I noticed and perhaps why my boss gets fruatrated when her college aged daughter uses it, is the hold on the card factor. It holds the initial fee. Then you are charged the fee, so it's like holding twice the amount if that makes sense? It realeased and I only paid what I actually used but it was still a day or two. Fortunately it didn't wreak havoc. Other years and times in my life it really could have.
The driver was pleasant. I liked seeing the tracking feature available. I'd use their service again if opportunity arose.
