I never write these but should and this product deservers some praise. I bought the Canon brand and after a few months it started draining batteries like mad. I cleaned connections and it would be good for a day and then just start eating batteries and quickly within no time at all became useless.
I went to amazon to buy another one and saw this brand, skeptical I read the stellar reviews and said heck for 30 bucks or so it's worth a shot.
Now I hope some poor Chinese person was not whipped into cranking this out but since most of this stuff is made in Asia not much I can do about that except write my congressman and pass on videos and articles of mis treated employees.
At any rate I'm buying two more just for the convenience of having batteries ( I use rechargeable AA) at the ready.
