Heat WaveMade in USA: HEAT WAVE Instant Reusable Heat Packs- Back/Shoulder/Neck (6 x 18”), Reusable Heat Pack for Muscle Aches, Pain Relief, Click Heat

Great heat product for my neck. Holds the heat great .Could not find a replacement for my old similar product untilI found this on Amazon. Thanks

My husband used the product the first day he received it. It worked well and did it's job. I put in boiling water as instructed to get it ready for the next use. I put it on our drying mat. I came through the kitchen a while later and it had "recrystalized" and exploded. I couldn't even find the spot it had come out of. Very disappointed!!

While not the recommended use I’m sure. Similar products are sometimes used in cold water wetsuit diving. 50 degree water. Works well for that purpose!

The Heat Wave neck wrap does what it says it will do- it provides good heat and is good for situations when you need instant heat and don't want to be tied down with a cord. The problem is that EVERY TIME you use it you need to "recharge" it by boiling it. It is large enough that it needs a large pot to fit into and it is not flexible at that point so you can't just force it into just any pot. You have to wrap it in a towel, or put a towel into the pan. Its not a huge deal, but after one use and "recharge" mine has sat in my bathroom closet waiting for the next time that I really need to have the freedom of cordless heat. I'm "saving it" for an occasion that is worth the after care. If what you need is cordless heat (about 30 minutes of really good heat) then this product does what it says. Just be prepared to recharge every time.

This product really works great. When you have a sore muscle or ache and want to apply some heat even after you boil it and it's hot, you can use it without pushing the button.

I talked to someone that has had one of these for a number of years. He loves it, which is why I bought it. Haven't sued it yet, but looking forward to using it.

We wanted to like this so much. The first couple times we used it, it was great. (After using it, you have to boil it to get it to return to it's normal state for the next use. This is a little bit of a fuss to do, but worth it for the benefits.) On the 3rd time using it, it leaked all over my husband's shirt and the fluid inside the pack actually BURNED HIS SKIN! Our toddler almost got his hand on the leaking fluid as we scrambled to clean it up. A product this expensive should last more than 3 uses. Incredibly disappointing, cannot return after about 30 days. Not worth the risk. It also got on our couch and in turn ruined all the fabric it touched. It hardens as it stains. Don't waste your money!

I buy these every year. They get hot fast and stay hot for a long time. They are so convenient, my boyfriend and I use them to get warm, for sore necks, for sore backs, for muscle strains. After long periods of use they may eventually leak, and have to be replaced, but we love them.
