The leak detector looks pretty decent. Included battery and pick to replace the battery. Bottom two contacts through which a leak signal is applied

Very good image quality as night vision option, what leaves me in doubt is how long does the internal battery last? And how long should I charge it

She is to relook good now try or it succeeds hope of being happy with it Danku

Not terrible, the rfid circle reader that worked on Monday does plus focus on Tuesday the fingerprint reader works for me but does not work for my woman the code works.

Fast delivery. Connected quickly, the first time. Mount only for 3 M tape. Works, as described.
