As a Walmart associate, I was happy to find them on our Walmart.com for sale. I had seen it advertised somewhere and I found it on Amazon, but then I searched my Walmart and found it. I thought they would be very useful for a plumber and an electrician, so I bought a set for both of my sons and one for each one of their employees for a Christmas present. They are rechargeable and each pair comes with a cable, so no worries about those expensive button batteries like another style had. i think they may be able to be worn over work gloves as well. Thank you.
