It gives the actual live feed to a great deal of useful Ebay information such as product specifications, customers’ feedbacks, and past product sold. **What do you dislike about Countdown API?** For me, there is one or two things that I feel are a little restrictive in a way; this is the aspect of customization. The filters set by the producers for the products searched do not necessarily meet my needs most of the time. **What problems is Countdown API solving and how is that benefiting you?** Countdown API simplifies this process for me, it saves me hours of work besides the fact that it provides accurate data.
