Easy to Use. Great for Winter Morning Walks.  Awesome Price.
No longer need those disposable warmers.  I bought this for my mom to take on her daily walks.  She uses it daily.  Mom is not a techie so she likes things that are simple to use and this hand warmer is very easy to use.  She uses the same USB-C plug as her phone for charging so no need for extra cables.  There is only one button and the indicator lights are easy to understand.  Blue LED lights indicate the battery level and red LEDs indicate heat level.  At the highest heat, this thing gets HOT.<br /><br />I recommend this product.
