With my machine, I found that the FrogTape Released much better than the blue tape. It felt as if I was going to break the glass with the blue tape. The prints released better with this tape but had no issues with non-sticking. I also do not have a heated bed either. Most of the time I can get several prints without having to replace the tape. The blue tape easily ripped off or stuck to the print. This is just my personal experience with my cheap XYZ Davinci Jr. I have not tried it with any other machine. So your mileage may vary bc all machines/filaments are different.
