Title: Fantastic heat therapy.
Review: I have used these instant reusable heat packs for a few years now. Yes, you have to boil them in water to reactivate them but they always heat up to the perfect temperature every time. I use them with a moist face cloth to help relieve an eye condition that I have called Blepharitis, a side effect from lasik eye surgery. I use them everyday, in the morning and at bedtime. I own three pair.
