60 Large Heating Pad With Vibration Modes

some mornings i wake up and back pain develops through the monring. in my case, its not always sore right when i wake up and even while my chair is very comfortable, sometimes i need more than good lumbar support. I am very pleased with this heating pad. Overall i think its at least 8.5/10 sometimes and the '5 stars' pattern doesn't always give the flexibility needed. I am going to list several cons so i wanted to get this out of the way at the top. It is very good and helps a lot, there are aspects i would like differently but none are a game changer. The unit comes with an 8000 mah battery that can be used to power more than just the pad, and that is nice. it also can use other similar batteries. This is great because in my case, while you can get about 3 hrs on a full battery charge for the included battery, my battery gets too hot if i have both heat & vibrate on full and 2 hrs at a time is all it can handle. I can swap batteries and continue and when the other cools down swap back to it. I could also use a usb wall plug and not worry about the battery, but where my desk is, that's not convenient due to the cable length & location. this is not really a limitation of the unit but my office. It is very nice that the cable is on the right side, so if you were to wear it while driving you don't have to have the cable across your body to go into the center console or dash. on that note if a longer usb A cable were included, and a wall plug, these would both be welcome additions, but i don't mind that they aren't. I have plenty of both anyway if i want to change it. The pocket fits perfectly an Anker A1263, and I could also use my A1287 but it is a bit tall for the pocket so due to the weight i only tried it once. the vibration patterns are not as pleasant for me as a steady constant vibration. There is not a way to choose a pattern if you like one, and the low/med/high really only change the intensity. some 'chair back' style give this kind of options. If you aren't using the vibration, the location of the motors you may need to shift around a bit before you find what is most comfortable. this is only a minor thing for me. my chair does have quite a lot of lumbar support and if you are in a recliner it may not be an issue at all. I found it was much more comfortable to have a T shirt between you and the pad, i know it says it is soft to your skin and it is, but this worked out better. I wouldn't try to use it over a sweater or jumper though.
