    Rubbish, only good for a couple of uses
  

*by C***T on Reviewed in the United Kingdom on 17 February 2019*

Bought a 2 pack of these.  The first one failed on its 2nd or 3rd use and started leaking.  The problem being that the welded seal around the perimeter was much too narrow, and it separated open.  The 2nd one lasted a few more recharges, but then developed some imperfections inside meaning that it was impossible to properly recharge - no matter how long you boil it for, it never went completely clear, and thus re-crystallised on cooling.Nice idea, but poorly made, so waste of money.

### ⭐⭐⭐⭐⭐ 







  
  
    Simple and Effective
  

*by O***K on Reviewed in the United Kingdom on 22 December 2015*

Good service from the vendor, no problems with the packaging or label.Item does exactly what you would expect, and produces enough heat to keep me happy on my Winter hiking trips.On testing, I found a good heat for about 14 minutes, gradually tapering off to ambient surrounding temperature at about 29 minutes. Recharging is as stated in the description. I first bought a small pot of water to the boil ( in this case 1.5 cups of water in a 10 cm Zebra Billy Can ) with a small handkerchief in the bottom of the pot ( to protect the hand warmer from the heat of the base ) removed the heat source and put the hand warmer in. Took 5 minutes and 44 seconds to return to the liquid state so that all of the crystals had melted and I wasn't running the risk of the pack still having solid crystals in it and restarting the chemical reaction when I took the pack out of the water.Meets my needs and is used regularly.

    Great hand warmers for the price
  

*by B***N on Reviewed in the United Kingdom on 30 January 2021*

Bought as a gift for someone with very cold hand and they love them! They're easy to use and great that they're reusable, although it does take quite a long time to fully recharge in the boiling water. They have been recharged several times already with no sign of degrading, however, it is expected that they would become slightly less effective over time, hopefully not for a long time yet though!
