The fleece material of the blanket itself is good, the stitching and overall quality is good, color very nice. Good long cord on it.
Now the biggest downside is that this thing just doesn't get very warm. Used it over top of me on the couch for 45 minutes and didn't feel anything. Put it under me (sat on it) on the couch, with a regular blanket on top of me, and then after a half hour of watching TV I realized it was somewhat warm and it was working, but it never gets beyond "warm" and you only get that warm feeling if you sit on it and use another blanket to trap the heat in.
That doesn't make it useless in my book. On the plus side it seems to be fairly efficient. It only draws 27-38 watts according to the lithium power station I have been using to run it. I don't know exactly how many hours total its been ran but my 288 wh battery pack (very roughly 19ish amp hours) has been running it off and on for at least 8-10 hours total and as I type this I still have 23% battery left.
One unfortunate note I have come to notice is that a portion of that 30-some watts its drawing is being lost right at the tip of the power plug. It took me a long time to notice, but I've discovered that whenever I unplug it the tip of the power plug is hot to the touch. I've tried this with a couple different sockets now on different power packs, all with the same result. Electricity is not being transferred efficiently at the tip of the plug, causing it to get hot, and the tip of the plug is NOT where we want the heat/energy to go! This is energy being lost before it make sit into the blanket to warm me. So if the overall draw is 32 watts, based on how you can barely touch the tip of the plug without being burnt I'd guestimate that only 20ish watts is making it into the blanket. That stinks. I very well might cut the end off this and use a different connector for it, like an andersen plug. The 12v cigarette lighter plugs we are used to and find so convenient were never designed or intended to be used as power connecters the way we use them today, so I won't dock the blanket overall too hard on that because they can't control the fact that 12v cigarette ports have accidently become the defacto 12v accessory port of choice, but it is still something I figured I should share.
Because my battery pack tells me the wattage being pulled I am able to observe that this blanket DOES HAVE some kind of regulation in it, because once I was sitting on the blanket with another regular blanket over the top of me watching TV for a few hours I began to notice that the wattage draw from the blanket would occasionally drop to 0 watts for a few minutes, then it would go to 30-some watts for a while, and back to 0, and repeat. So it DOES have some kind of self regulating feature, which makes it very efficient with my battery pack when used properly (ie, underneath you with a top layer to trap the heat).
I was going to say that the blanket doesn't appear to have any low voltage cut-off for battery protection, but low and behold just now at 10.35 volts the blanket's red LED is still ON at the plug but my battery pack shows no current is being drawn... I've given the blanket a few minutes in open air to cool down and.... ope... well folks now the blanket is on again drawing 27 watts, and my power pack is down to 10.1 volts so it seems the blanket was simply up to temp and not drawing because it was regulating temperature. So I will confirm that there is NO low battery protection in this blanket's circuitry, if left on it will run a battery beyond dead and probably even beyond the point where it could damage your battery, so keep an eye on that.
Also there is no switch or heat settings. Plugged in is ON, unplugged is OFF, and thats the only control you get (plus its built in regulation).
If you are only partially sitting on it (ie, on a computer chair) and the part of it that reads temp to regulate is not underneath you then it will basically just run steady but it still never gets "hot". Warm, but not hot.
All that being said, the temperature that it self-regulates to is pleasant. Although it is very slow to heat up, I think it is perfect as something to lay under you in your sleeping bag for camping and even though it has no controls the temp it levels out at is comfortable and the fact that it will shut off at a certain temp means a modest battery or power supply will keep you warm all night without wasting any extra electricity.
Its decently pleasant under you on the couch for TV but simply too slow to heat and not hot enough that I don't think we will use it much for that other than the testing I have done for this review.
So in conclusion... I got this dirt cheap on deal of the day, combined with a rewards certificate, so I paid almost nothing for it and at that price I am happy. As I said this would work perfect for camping so long as you use it properly bundled up with other layers. The downside is I think that is really the only valid use I will have for it, it is far to slow to use for passenger comfort in the car unless you are going to be on a road trip for 2+ hours and that is a non issue for me (my car has heated seats anyways).
If you can snag a good deal and understand its limitations, go for it. At full price expecting high performance, keep looking for another option.
