Worked well enough..heated up a bit with 3 devices charging and stopped charging an ipad. Unplugged it for a bit and it worked fine again.

Does what it is meant to, though sometimes gets a little brown/crispy on the bottom when in warming mode for a few hours.

Fits well, but not as warm as I would have liked.

It is ok. It get warm sometimes and stays on. I have to unplug it and wait a little bit then plug it back in.

Works well, not completely reflective like the photos suggest. Helps reduce heat, too.

Yea it's a bit of loose threads but for this cheap, not that bad. Had to go take a hike and it rained, this think kept my neck very warm. Careful to wash as the colour on the black thread may bleed.

Don't expect to heat your entire house with this but it does the job if you just need a little bit of warmth.

Overall, this product does what it is designed to do. It keeps my face and neck warm when riding my bike to work in the Wyoming winters which means wind chills well into the negatives. There is excess fabric around the neck, but it does help ensure that there is enough overlapping to keep wind out. I found the ventilation holes to be oddly positioned for my face. It takes some work to get the holes over my mouth without the eye area ending up in an odd position on my nose. This would vary person to person based on head size. Condensation builds up either way, but that's to be expected. I like that it is thin enough to layer under a helmet and is comfortable enough to sleep in while camping if needed.

A bit tight.  It comes as advertised, but it's not super warm.

works as described.  Did get a little warmer on the charge transfer though.

Good to keep my feet warm, but doesn't cast a lot of heat.

Fits as expected. A little bit too warm if used to go jogging.

Nice product.  Warms well. A bit cumbersome to hook up, but the price you pay.

It does what it's supposed to and gets cool when body heat is pressed against it. The material is pleasant (doesn't feel too plastic-y). I would love if it came in some colors aside from royal blue.

It's not as warm as I expected, but it does keep my hand from freezing when I'm at my computer.  I wish the heated part covered the whole top though

I bought this as a running shirt. I've been wearing UA heat gear short sleeve and on long runs in the heat, the sweat doesn't evaporate fast enough and the shirt clings to me. This was a definite step in the right direction, but not perfect. It is cooler and the fabric seems to be lighter and aid evaporation more, so that's good. It's not quite as much as I'd hoped, so I'm still looking for the perfect solution. The only other fault is that it is unusually long, 2-3 inches more than the short sleeve. After a little home trim job, it's been fine. This is a good shirt for the money and I'm glad I bought it, but it's not perfect for my needs.
