The four play massager is not the greatest massager I have ever used or tried. Would not necessarily recommend to anyone.

This toy is exactly what it claims to be: a massager with four attachments that can enhance foreplay. If you're shopping for a clitoral vibrator, this may fall short. If you want to work knots out of sore muscles, this is a good, affordable product. It can be counted on to arouse oneself or a partner, but don't expect more than that from this product.

In all fairness, this toy and its attachments are well suited for tired or aching muscles after some "heavy activity." I did use it on my neck and shoulders, and it felt rather nice and I'm sure it would work well on the lower back as well.
