All, I get some ball burn especially after a night in it. I have some ball burn with the happygo but nearly as much with the HT. I don't think the ring is wrong as I have no issues getting in it. Balls do not go numb or anything but I just don't know what to do. I want this one to work as the tube is perfect!!! I use some cream which helps a bit but looking for advice.
on the ring of holytrainers there is a casting mark, a line where the molds for the casting met, if you havent sanded it down it can irritate your skin. It might feel not sharp when you touch it but its more than sharp enough for your scrotum
