I don’t think they “fix” anything. So personally I would never use them. That being said, I think they can create a short term change (decrease) in muscle tonality, so they MIGHT have a place used in conjunction with other modalities.
The only benefit I could think of is causing some blood flow in the area which might indirectly aid with recovery but that’s about it. Still wouldn’t waste my money on them though.
Which reminds me off a funny story coach Eugene told not long time ago. I think he said that he have heard some other reputable coach having found out that some specific sex toy had worked out as well if not even better than that device 😀
