IF I knew how to use it, it might be great, but there are no workable instructions

Maybe not fair to post review yet as I have not used this yet, but I have not used because it didn't come with workable instructions! the "instructions" were very brief and very technical, not written for a layperson. I might amend this review if I can figure out how the thing works, and it works well, but meanwhile, it doesn't work at all since I have no idea how to use it. It's lucky I gave 3 stars. Probably should give 1 or 2 for now.
