Pros
Flexibility, in my area at least. Decent wage, if you can get done on their impossible schedule.
Cons
I've only delivered for Flex for a few weeks, however, I have delivered in other capacities. The app seems to need a lot of work. I'm not sure if the app gets its info from google maps, or if it's a standalone kind of thing. Either way, it will run you in absolute circles. Example: You can't see you entire itinerary for the day unless you stop the delivery you are doing at the moment. So obviously you can't always see what's coming up. For my first 3 delivery days, I quite literally would deliver to say, 100 Main st, go to my next delivery (3-4 blocks away), do a few more deliveries, only to have to come back to 102 Main st later in the day. I seem to average 10 deliveries /hr, which sounds pretty decent. That is until you have a day with 50 deliveries, you're on a 3hr block (which is all my delivery center seems to offer), and you have to travel 40 minutes North of the dispatch center. You do the math. If you happen to lose mobile data on your phone going through a bad cell coverage area, you may as well pack up for the day. Almost every day this happens to me, and although my cell coverage is not Amazon's fault, the app obviously is. If the app loses its precious data link, you'll see more crashes than a NASCAR Rodeo. No lie. I spent 10+ minutes driving around in a highly populated area (dodging pedestrians, and small pets), constantly looking down at my phone, back up to the street, back to the phone looking for a good cell coverage area. Because otherwise the app kept saying "In 500ft...(huge pause)... In 300...(smaller pause)... In 5...5... In 3...In 400ft, make a legal u-turn (no lie, the app tells you to do that all the time). Only to get somewhere with coverage and be told to do another legal u-turn and head back to no LANs land. On the subject of "Help /support" it really is just as bad as everyone says. I had an issue with my phone (not the app, my phone) to where it would not connect to either mobile data, or any Wi-fi's, even though I could see them, and they had a guest account, under normal circumsatnces, I could use. It was about an hour before my delivery block was to start, so I called help to see if I could forfeit the block over the phone (they ask if you need to forfeit, please do so 45 minutes before your delivery time). Without cell data, I can't get into the app to forfeit the block, thus why I was trying to call to forfeit. The young lady was very nice, walked me through everything I needed to do. Everything seemed OK. Then 2 days later I was e-mailed from "support" asking why I had "abandoned" my block for that day. To clarify, Forfeit means you have followed all the rules, and you and Amazon agree to relinquish your delivery block, no harm, no foul, to another driver who would like to pick it up. Abandoned means the same as a no-call, no-show. Really bad. I explained the situation with the phone, and how I called "Help" because without data, I couldn't forfeit the block. The response e-mail I received, walked me through how to forfeit the delivery block through the app!?!?!?! Wow, just wow. Not just once, but twice I received the "Here's how to properly forfeit the block through our app..." even though I had explained the idea that I had no internet of any sort. Catch 22, so app user beware.
