Looks perfectly true, but too slowly flashes

As against the interior finish is very light, the son of glue everywhere. It does not prevent the proper functioning, but we see that it's very cheap. Finally for the price, I do not expect more.

What bothers me is the slow flashing red LED. This is a problem because between two ignitions, slaked phase lasts a few seconds. A thief can move his head to the window, watching a brief moment, and do not see anything, no light, it just falls into the dark phase. Especially since the LED is not powerful. So you can miss without seeing it.

So deterrence is only partial.

The battery life is very long battery charged in July ... still active six months later.

I do not advise to you if the led is important (and thus whether it should be visible in the dark). If it's mostly against by the visual effect of the dome you want, then this is perfect.
