Product review (1 stars): Worthless
I thought I was re-ordering one like those two I had ordered previously. It looked the same, was priced the same and those two are still functioning as expected.
Unlike those, this one arrived without the two little button batteries to power it. Those same type declared dangerous to children, due to being a swallowing hazard. Perhaps this is why they were not shipped direct mail from China, I don't know.
Perhaps that is why they are not available here in my area, I don't know that either.

 I DO know it would save time, money and hassle to simply go back and buy the one I originally purchased, instead of fooling with locating those batteries and having them sent instead.

 I see now I failed to review that product and will now do so, as it has had some unwarranted (I feel) reviews. After 7 months of stellar performance from both of them I feel I can give them five stars with some degree of accuracy..
Unlike this one, those you just place where you desire and they begin working. I don't know what to do with this one. It is not heavy enough for a door stop, too thick for a bookmark and not enough of a big deal to worry about.. So I'll just chalk it up to "Live and learn" while you benefit from the sideline, hopefully. .
