Conclusion
I was excited to get this and I'm excited every time I get to use it. It does take time to pull a vacuum so it's much better to sit down and enjoy with a partner or while watching a good video. This isn't an auto-stroker, it's not a sprinter, this to me is for a nice log unwind. It's a totally different experience that's a little slower and less intense but very pleasing. As the vacuum is pulled there's a bit of a motion that pulls your penis in and it sort of strokes, but only about an inch or two of movement over one or two seconds. It's not wet, sloppy, and rapid like a good blow job, but the best thing I could compare it to is a blowjob but only sucking. The heating is fine, but didn't make much difference to me other than run the battery out, and absolutely under no circumstances should you ever actually put headphones into the headphone port. Just don't do it. Tell yourself it's only a charging port and move on.
