I STARTED USING PURERELIEF HEATING PADS YEARS AGO AND I WILL NEVER USE ANOTHER BRAND AGAIN.I am a chronic pain sufferer. I have dealt with intense pain for many years and have bought, probably, more than a dozen heating pads over the years (dozens if you count the ones my parents bought me until I started working). I see a pain management specialist, monthly, who has been able to offer relief in the form of medication and epidural pain procedures. That's all great and effective. But none of it is 100% relief. I still have to be very careful with my activities to prevent further pain, and I often am not.The physical limitations of chronic pain sufferers can be frustrating and you just want to be able to do the things you used to do. But that often results in a good deal of pain that surpasses the ability of medication, alone. There is always some pain that only a good heating pad can relieve.After years of purchasing cheap, plastic heating pads that crack and fall apart (you know the ones with the cheap fabric sleeve that snaps shut to keep the plastic in place), I decided to try the Pure Enrichment brand products. I was very impressed with the softness, the flexibility (as the wiring is integrated into the cushiony pad) and the many levels of heat that PureRelief heating pads provide. So I made my first purchase. IT. WAS. LOVELY. Cozy and soft; like being wrapped up in a warm hug that pulls all of the pain out. Unfortunately, a family member noticed how blissful I was in my heated cocoon, and they borrowed it and never returned it.In 2017, as my chronic pain issues had increased, I again found PureRelief heating pads on Amazon so I ordered two (Neck and Shoulder and XL - King Sized). And I was just as pleased (perhaps a bit more) as I was with my prior purchase (their R&D must be in a constant state of development and refinement because they only get better). I used my heating pads on an almost daily basis for about two years. I used them for soothing my pain at home, I took them to work with me for back and menstrual pain relief, I even used them to warm me up when I was chilled. Then, in 2019, they both stopped working. I tried resetting them, resting them, cleaning them...all to no avail. I assumed that I had overworked them (because, let's be honest, I had. I used them every single day) and put them to the side, but I still couldn’t throw them away.This Summer (2021), in desperation, I called their customer service hotline, just to see if I could get some tech support to get my heating pads going again. The customer service agent who answered the phone asked my name and the order number, which I provided. Within 1 minute, without any need for further conversation, she said that she had just placed the order and was shipping replacements to me immediately. I was shocked. It was just too easy. That's it? All I wanted was help to fix the pads that I had. I have NEVER, before or since, had such an easy, pleasant experience with ANY customer service agent. It's usually far more complicated. I felt really good after our interaction and was just thinking about how awesome that was and realized that I had forgotten that Pure Enrichment has 5 year warranties on the heating pads I purchased (which is part of what attracted me in the first place)!!! How smart was I?! Haha.Within 2 days I had two brand new heating pads delivered to my door and I continue to use them on an almost daily basis.REVIEW:I LOVE PureRelief heating pads. They’re amazing and I will probably never buy another brand again.PROS:*The Customer Service is top class. They are smart, professional, patient and kind.*Pads heat quickly so pain relief can be soothed much more quickly than with other heating pads.*The Neck and Shoulder pad has only 4 heat settings, but I suspect that is for safety reasons. I consider this a pro because the pad is designed to provide relief; not to pander to potentially dangerous requests.*The moist heat and the heavier weight of the pads allow the heat to really penetrate into the muscles nicely.*The King XL has 6 heat settings AND provides you the option to either use Auto shutoff (where it turns off after 2 hours) OR to turn off the Auto shutoff and receive constant relief until you choose to turn the heating pad off.The soft, coziness of the micro mink is very soothing and the flexibility of the pad itself is luxurious.CONS:*The levels of heat are sometimes not consistent throughout the whole pad; mostly around the very edges.*The Neck and Shoulder pad, while amazing on shoulders and upper back, doesn’t seem to have any heating elements in the part that actually rests on your neck.*The magnetic closure on the Neck and Shoulder pad is too tight. The concept is great but it needs to allow for larger sized necks.*While the weight of the Neck and Shoulder heating pad is good, it would be nice to have straps that wrap around to the front or that can be wrapped around the upper arms in order to keep the pad securely in place.P.S. I’ve included pics of the XXL that I recently bought, which ALSO works like a dream.
