Sunny Bay Lower Back and Shoulder Joint Heat Wrap with Strap, 10"x18" Heat Pad, Microwave Hot/Cold Pad, Reusable, Portable, Navy Blue

I owned 3 microwave heating units previously. One is a rough kind of fill (popcorn I think). I don't like it because it is not soft and comfortable so I don't use it. Another is filled with flax seed and is lovely except it has no ties and just is placed so you can't move around but otherwise like it. The third was similar to this one. It was filled with flax seed (my personal favorite). I had it for many months and loved it and used it daily for my painful sciatica. The last and final time I used it, I went to reheat it and must have pressed the wrong timing. A horrible smell filled the air and I ran to the microwave. There was still 7+ minutes on it. Who knows how long I set it for. I know I should have watched it the whole time but being impatient I didn't. I paid the price by losing the pad and having my microwave and house smelling offensively from the burnt product. I really need it so promptly went to Amazon (my lifesaver) and found two more with ties that looked good. The first one came the very next day and I liked the moist heat but the ties were not sufficiently long for my husband's or my waists. It tied but did not stay where we wanted it too. I only hoped the second one I ordered would work well. That one came the next day and fit well with long enough ties for it to stay put. It is comfortable and just a delight to own. I will let my husband share it because it really truly helps. Pain meds don't touch it but this soothes and does help. I'm sorry I didn't order two of these instead of one of each kind but I didn't know the other wouldn't have long enough straps to work as efficiently. However I'm grateful to get such a fantastic replacement and thank you for your wonderful product.

I only used this pad as a heating pad and I love it. It delivers a smooth, consistent warmth that lasts far longer than I expected. The heat feels deep and penetrating, which really helps relax my muscles. The hands-free design lets me move around while still getting relief. Honestly, I couldn’t ask for a better heating wrap—this one checks every box for comfort, effective, and easy to use. Definitely money well spent.

My wife used it for her sore back and she said it works well. It's a bit heavy but it's big so it covers a fairly large area. The ties don't have Velcro; you have to physically tie the ties to hold it on.

I absolutely love this microwave heating pad. This is a moist heat, flaxseed-style warmer, and it holds heat significantly longer than an electric heating pad. According to my physician, this type of heat penetrates deeper than electric heat—and I can honestly feel the difference. When I wear this on my lower back, I relax almost instantly and usually fall asleep shortly after. The warmth is soothing, not harsh, it's very sturdy and it does exactly what it’s supposed to do: relieves tension, loosens tight muscles, and promotes deep relaxation. I’ve also been using it on my shoulders with great results. It was highly recommended to me, and now I understand why. This has become a go-to in my self-care and pain-relief routine. I’m already planning to go back and purchase the neck-specific version in the next couple of weeks.

I’m in my third trimester of pregnancy so everything hurts already, and in addition to that I’m an avid knitter prone to shoulder pain which is exacerbated by pregnancy. I’ve tried electric heating pads, homemade rice packs, hot/cold gel packs with velcro straps, and now these. These are it. The straps are just elastic enough that they flex with your body once tied and stay in place. The moist heat from the flax seed is far superior to electric heat from a plug in pad. I wish these held heat longer, but for a microwave heat pack they perform well enough. A removable and washable cover would also be an improvement. The straps are long enough for me to tie anywhere I need. I wear a maternity 8/10, for reference. When not pregnant I’ll wear 4/6, and I’m sure these will be more than adequate.
