Sunbeam Cordless Rechargeable Heating Pad, Portable 9.5" x 12", Machine-Washable, Pain Relief for Back, Shoulder, Neck, and Period Cramp Pain Relief, Gifts For Mom & Wife, FSA/HSA Eligible, Slate Grey

I've used mine for winter months for 2 years to alleviate lower back pain caused by cold air. I consider it to be a bargain and would purchase another if need be. My minor complaints are the battery is not in an ideal location and does not hold its charge when set on the highest of 3 heat levels. This shortcoming can be solved by not using the highest temperature setting, which I seldom use. Also, the Velcro on the strap is smaller than it could be (2 inches by 3/4th of an inch) and therefore will come lose if the strap is stretched so that it is nicely snug to your back (which makes a real difference in very cold air). It would be a major improvement if the width of the Velcro is enlarged. I solve this problem by wearing a tight-fitting sweater over this warmer and under a coat, which is also excellent for layering in really cold weather.

This worked WAY better that a heating pad with a cord!! Just the perfect amount of heat in a reasonable amount of timeThe only problem I have with this and this could just be a safety thing but how short the battery life is while on full charge, I think this could be a small fix but that’s not my callJUST TO BE CAUTIOUS!! This is to prevent anyone for making this mistake:Do NOT leave a charged battery plugged Into this pad and leave it wrapped in a bag. It will short out the page heaters. Unplug the battery first 👍🏻✨

I used this product to help relieve menstrual cramps rather than back or shoulder or back pain as mainly advertised.Because of this I had the pad sitting more on my stomach/pelvis area, so it could change some of my experiences.The heating pad charges at a fairly normal rate, taking about 3 or so hours to fully charge. At the lowest setting you’ll get about 3.5-4 hours or so of use before you’ll have to charge it again. If you change the setting to the medium or high settings you will get less time, about 2-2.5 on medium in my experience or about 1.25 hours on high. If you switch between the settings while you’re using it the amount of time you’ll get for that charge changes, if alternating between low and medium I’d say you can probably get about 2.5-3 hours in my experience. Using the highest heat at all will suck the battery very quickly and greatly limit the amount of use you get out of it that charge.It should be noted that the low and medium settings are sufficient to reduce discomfort from cramps to a reasonable level. I would not recommend using the highest setting for very long as it gets, and I can not stress this enough, extremely hot. I can usually only keep it on high for about 10-15 minutes at a time before I have to switch to a lower setting. It has its purpose and is really good if you need more heat but it is for sure a big step up from the medium setting. On a scale of 1 to 10 where 10 is the hottest heat you can handle I would put the low mode at about a 3, the medium at a 6 or 7, and the hot at a 9 or a 10. None of the settings are bad but I would take the high setting in very small doses, as it is effective but also very efficient at heating up and will be hot almost immediately.The heating pad maintains a consistent heat/temperature output for whatever setting you have it on. It also heats up very quickly so it is very helpful when you are looking for near immediate relief.The velcro strap allows it to fit a wide range of sizes and holds the heating pad securely to the body. It’s adjustable and stretchy so you can get the heating pad very firmly against your torso but not have the band squeezing you uncomfortably like some other elastic straps are known to do.If you intend to put this more on your pelvis like I did I would suggest trying to put the elastic band just under the widest part of your hips for the best hold.It is indeed portable and easy to work around the house in. Allows a good range of motion while still providing relief.Overall very happy with this purchase.

I get really bad menstrual cramps that usually leave me chained to the bed because roasting under a heat pad is the only thing that really helps. The old heat pad I was using has to be plugged in so it was very inconvenient having to be laying around all day to avoid being in pain. This portable wireless heat pad has been a huge help because I’ve been able to be up and about, making bread and getting things done around the house all while wearing this discreet little pad under my clothes! It works great to keep my cramps at bay, is very comfortable to wear and you can easily wear it under a baggy shirt and no one will even know it’s there. I even made a run to the grocery store wearing it and I feel great even though I got woken up by that terrible feeling of my insides churning last night, but wearing this heat pad all day has been keeping the pain away efficiently and in a very convenient way that allows me to go on about my day instead of being stuck laying around for hours :) the battery could be a little better, but I’ve been able to wear it on the medium heat setting for probably about 3 hours before it died and it already gave 3 hours of being able to do things instead of being in pain, so I will still take the win because considering the price I feel like that’s not a bad deal! Charging it up so I can wear it again in a few hours when it’s fully charged is no biggie in my opinion. 10/10 would recommend!!!
