The electro rings are good quality and to me they seem to apply the Estim better than the loops. However, I think they would be improved if the large ring was hinged in some way. I have trouble getting it over the equipment. In addition, I think the black separation block should be wider so the testicles don't get squashed as much between the two rings. Don't get me wrong, I love the product, but it could be better.
ADMIN: Thank you for your feedback and it will be passed on.
