The Relief band is the greatest thing I have ever bought. It really really works for me and it is adjustable and no side effects, can't say that for the patch which you can not take if you have high blood pressure or if you drink. The thing is buy the one that you can replace the batteries or the rechargable one not the disposable one.
My husband and I swear by them.
They also help a great deal with stomach flu or medication nausea, they were originally designed for Cancer patients.
