Is the delivery speed of uu errands fast? How long does it take to get to the same city?

In my conscience, the delivery speed of uu errands is really fast, which is slightly better than SF. It is very important to send documents to customers last time. Less than two minutes after uu ran errands to place an order, the master came to pick it up. It's the first time to use this software, and I feel unreliable. The result was delivered within 30 minutes. The master is really agile. I am worried that the express delivery will be completed so soon before the email is sent. It's really a business trip Later, I checked that uu errands and other express delivery in the same city can maintain such a fast delivery speed mainly because its delivery process is very simple and will not delay time. The errands will be delivered directly after receiving them, and there is no need to go to the transfer station to collect and sort them out, which wastes time and increases manpower.
