I've been using Rival Ripper for the past 2 years. I tried the software on a trial and had the chance to use all the software's features. I could cancel anytime. Because the software had all the features I needed, I signed up for one of their monthly plans. I've made my eBay business better ever since.
How was the support? Back when I was starting, I had a few questions. I emailed their customer support and received responses in no time. I didn't have anymore questions after signing up for a monthly plan.
