“A zapper cost between 1/3 of a cent to 3 cents per 7-20 session in battery's weariness.
How much sessions can you pay with the additional cost of a wall plug powered device ? (they are usually quite expensive. Not the wall plug, the “improved zapper”)”
I had two brand names in mind.
Yours was one of them.
I’m very interested on knowing what “catch” your interest, when making your choice for this one.
