Current Solutions InTENSity IF Combo
Great product. I originally got this one instead of the one with just TENS because I thought the IF would maybe be a little stronger, which is what my patient wanted. She ended up liking the TENS better, and she said it was stronger. She loves it, and it seems like a great product to me. Next time I order one, I will get the unit with just TENS, but I would order the InTENSity product line again - definitely.
