I tried several other slide show softwares, all of which, like Kizoa, offer a free version that works in a limited way. Of the free versions, Kizoa was clearly the best for my use and I did purchase the $100 version. I am very satisfied with it, now that I am pretty far up on the learning curve. I'm retired so was not "born with an electronic gadget in my hand" and did not have any previous experience with graphics software or slide maker software or video editting software, so I really was a raw novice. I watched several YouTube videos about how to use the software and found them quite helpful. Now I get raves on my slide shows and am confident I made the right choice.
