It has a battery, and doesn’t always need to be plugged into work.
[[VIDEOID:4db8e602e90dfe20b6133c1562962d3f]] Update- September 30, 2022:  I contacted the company through Amazon, they have sent me a replacement unit. It works wonderfully. I have updated my review from four stars to five stars. I am very pleased with the customer service that I received from the company.  This really is a great massager, and now the whole family uses it.<br /><br />Update- September 16, 2022:  So, last night I came in the room to find my husband using this massager. He wanted to know why it shut off, I had asked him how long he had been using it, and he said 15 minutes or so. I let him know it had an auto shut off feature and that it must be working.  He then asked me how long the battery would last.  I was confused, I told him it had to be plugged into the wall. He said, “No it doesn’t. Look, I’m using it without it plugged in.”  I do vaguely now remember that there was a battery sticker on the box that it arrived in. Now I know why. I have moved this up another star, because it is even more portable than I originally thought. The instruction manual does not mention this feature, neither does the product listing.<br /><br />Original Review:<br />I placed it in a recliner chair next to my hip, and it feels so much better. I have set it on the floor and put my feet on it, and I do like the motion. I do not like any of the tools that vibrate, so I appreciate that this does not have a vibration mode.<br /><br />Pros:<br />It has two speed adjustment.<br />It can be used with and without heat.<br />You can easily change direction by pushing the direction button.<br />The instruction says it has automatic shut off after 15 minutes. (I do not know if that is correct, because I am usually done with it after 10 minutes.)<br />It can be used at home or work.<br />It can be plugged into any 12 V plug, including a vehicle or a camper unit.<br />It is fairly quiet.<br />The last page in the instruction manual says that it has a one year limited warranty.<br /><br />Cons:<br />The instruction manual is different from the actual function of the unit when looking at the operating instructions section.  It does not actually switch directions, unless you push the button.<br />The left side of my unit, the heat was having an issue, it does not have any contact information on the instruction manual for warranty purposes, so I will need to go through Amazon.<br />It does not come with any type of storage bag, that would allow me to keep the unit clean while traveling and not miss loose the power cords.
