Hello. I did a search but didn't find any reviews of this very simple device. If there is a review please let me know and I'll delete this. The device I'm curious about is the FuFu Training Clips By SoftXpressions on Etsy. In their description of the device there is a link to 2 videos (one direct link, on in the comments) of the device being put into place. It looks fun but want to hear from any here who might have used it before purchasing.
