Works great. packaging was very secure. it does a great job after the first charge.
The only reason I don't give it 5 stars is because I have used it but it really doesn't provide any relief; on the contrary, it caused me discomfort and left me in pain. But maybe it's not for everyone. The seller was kind and eventually resolved my issue. Other than that, the product looks and feels like it's made with good materials and is exactly as shown in the advertisement photos, it's just that personally I don't think it's for me.
The product is very good, but the packaging arrived badly damaged.
The product made my wife happy.
