We just moved from Kansas to Southeast Texas and Spanish is going to be a huge helper for us as most of the population speaks it as well as English. I think it's easy to use and I like that there is a male and female interpretor. Sometimes he's easy to understand than her. The picture and words are great visual helpers.

I dont know why there are some bad reviews on this unit! I am happy that I have found this item. It is sturdy and made out of hard plastic. As you would expect from a brand name like Energizer.

WE USE THESE THINGS TO WARM OTHER THINGS OTHER THAN HANDS LIKE LION BATTERIES WHILE ICE FISHING. THE COLD LIKES TO DEPLETE THE CHARGE FROM MANY BATTERIES.

Recommended to all. Bag material was way higher quality than I expected, nice interior quality as well. I bought a small size bag, was a bit worry it's too small after I received. I had two scenario in my mind before buying this and worry after seeing actual size.

I used these in conjunction with lucid dreaming exercise with some success. Definitely worth trying!
