I was using their repricing tool (still am) and everything was going well so I figured let's try the feedback tool. I'm so happy I did!! Right of the bat I started getting 1-2 positive feedbacks PER DAY. Which we all know helps you compete better for the buybox. What I really like about it is you can set up all types of rule on who to send messages and when. This is very important! I'm very happy with it and the price is also very competitive. So what can I say really... If it works it works!
