Comfytemp Cordless Heating Pad with Massager for Back Pain Relief, Portable Lower Back Massager FSA Eligible HSA Rechargeable, Birthday Gifts for Women Men Mom Dad Seniors Christmas 3 Heat 30 Auto-Off

****IF YOU BUY THIS: first thing, use rubber electrical tape or light-duty duct tape to reinforce the thin power cable where it connects to the USB-A male adapter that inserts into the USB-A female port of the power bank you are using. Otherwise the cable will surely fray and possibly even break completely during normal use, making the belt's powered functions unusable. Reinforcing it right away will extend the belt's usefulness by months, likely years. This is a recurring issue with light-duty electronic devices sold on Amazon. Careful proactive attention to weak spots like this saves time, avoids waste, and reduces the need for warranty actions.UPDATE 2025-08-23The ALLJOY belt with a 10k mAh power bank sold elsewhere on Amazon is still a good option, but I've decided that this COMFYTEMP model with a 5k mAh power bank included is the best option, as long as you are willing to invest in the new generation of small form-factor, GaN-chip managed10k power banks that fit in this unit's smaller-size pocket. (The pocket's small size is not the deal-breaker I initially thought, after all!) Two of these power banks allow all-day coverage without worry. The extra ~USD $50 investment is well worth it for my peace of mind! The included 5k power bank can be used for other things or given away to someone, so it is not simply something to be dropped in a drawer and forgotten about.I've discovered that the holding down of the two control buttons to turn the heat & vibration features on and off has a hidden undocumented benefit: they turn the attached power bank on and off without needing to press the bank's own power button first. Since the bank's button can be very hard to reach while the bank is in the belt pocket, this makes the belt much simpler and easier to use.ORIGINAL REVIEW (edited for content)Ever since I learned that I fractured my spine, I've been searching for a massage/heating belt that is wireless, can run while charging, heats effectively, runs quietly, doesn't break down or fall apart quickly, fits well & the straps retain their stickability, has effective elastic sizing straps, and has a properly situated pocket that can securely hold a larger 10k mAh power bank.Admittedly, that's a very long wish list! Fortunately, out of the many such devices currently offered on Amazon (all manufactured in China), at least two remain in the running: the ALLJOY brand device powered by an included removable 10k mAh power bank, situated in a pocket on the belt; and the COMFYTEMP brand with a 5k power bank. With another 10k power bank or perhaps two purchased separately on Amazon, I can keep either running all day. Time will tell if they prove durable; I've purchased an Asurion plan just in case.Based on the criteria listed above, the unit under review comes pretty close to meeting all my needs, but still misses out in some key respects.The heat is good, but the fit and loudness are a bit below the ALLJOY model. The two control buttons are not very responsive; they need to be held down for a couple of seconds to get them working. I thought for awhile the belt might be DOA. (This may however be a feature rather than a bug, since the belt has no lock setting to prevent accidental changes.)Both run while charging, a big plus allowing tethered function at locations like home or in the car while the batteries charge.The deal-breaking problem is that the COMFYTEMP's pocket is too small to accommodate a larger form-factor 10k battery. I find that 5k batteries fit well, but last too short a time with these belts. I would have to keep 4 of them charged up and on hand to keep the belt running. I much prefer having just 2 x10k power banks on hand as I can with the ALLJOY belt.So this COMFYTEMP model is good, but I can do better with the ALLJOY for not much more money.

I haven’t had this long but so far I really like it. The highest heat setting is perfect for my back and the constant vibrations mode feels so good. Paired together my back feels amazing while using it. I didn’t like that the “instructions” only briefly touched on how to put it on and how to plug in the battery 🙄 I was relieved to see the questions to my answers about how to use it were on here. But I would’ve rather have this included in the paper instructions that come with. Because this page won’t always exist. Instructions on their own page or companys site would be better if they didn’t want to do the paper instructions. Overall it’s working great so far!

It does give good massage, it's comfortable to wear, but I thought it was going to have more levels of massages. The heating is good.The only thing is that charge doesn't last long but you could plug it in with a longer cord and wear it. It would be nice if they would give you a long cord in a first place!

LOVE this belt !! Cannot live without it! I have bought 3 in total . Not because it’s no good but because I wear it 12 hours a day . I have multiple battery packs for it .I had surgery for L4-L5 and unfortunately it did not work and I now have nerve damage. For the past year and a half I wear this from the time I wake up until I go to bed. I was told by my pain, doctor and Surgeon that the constant stimulating is causing my brain to be confused with the pain. At the end of next month, I will be having a permanent spinal pain stimulator in . But until then, I will continue to wear this. I’m able to babysit lift my grandchildren up. Go walking. Without it, I would not be able to. Heat I only use in winter. And sometimes I will even wear it around my chest for my upper part of the back.But mainly it sits around my lower back and it’s been a lifesaver for me!!

Love it!! Only had it for 2 days now and it definitely HEATS UP. So good, in fact, I didn't realize it was burning me to the point I got welts on my back until I felt them later. Now the reason I still gave 5 stars was because I didn't take heed to the previous reviews saying to not put it directly on your skin, which I did. So, user error on my part. And also, since I have a high-tolerance for pain, although it was getting really HOT, it felt amazing against my back. But moving forward, I think I'll wear it over my clothes lol

Takes about 1.5 hrs. to charge completely. If I use both the highest heat and the vibration, I get 5 thirty-minute sessions (2.5 hrs. of use) out of a full charge . Wish a charge would last longer, but it forces me not to use it periodically, which is probably best.

Purchased my item in July tested to see if all red light turned on and they did. Used it 1-3 times in July and red lights turned on, and was helping with my pains. Used it today August 27. After 2 weeks of not using it and now red lights don’t turn on completely only a section turned on. Product was stored in it original packaging box when not in use. I’m unsure what happened and disappointed that the red littles are not turning on. If you know how to fix problem, Please let me know. And if there’s not a fix this item is not worth it, if one will have this sudden problem after only a month. :(

It appears okay but the booklet that give instructions is very inadequate . It gives little info on hard to charge it . so far haven’t solved the problem how to charge it fully for heat or vibrationVery Frustrating !!!
