Cheap POS
For the first 2 uses, it would only work if the unit was 75% locked, but not fully. (If the battery cover was turned all the way to “lock” position, it wouldn’t work. The batteries had to be slightly “loose” to work.) The third time I tried to use it, it wouldn’t work no matter WHAT I did. (And yes, I remembered to turn it off previously.) Waste of money. Unless I just happened to get a one-off fluke.
