The price-performance ratio is very good.
It is working properly.
What I do not like:
For cable:
-The Cable is very thin: 1mm
So I have to live with "high" current fear, a cable melt. Do I have to try.
-The Red wire runs under the first battery and presses them consequently upwards.
-No Copper cable
To switch:
-The Switch protrudes
Therefore to take this criticism on my use a workaround.
For closure:
-When Closing the lid must be paid to DDN pressure exerted, otherwise most likely cancel the hook.
When the lid is lifted during close some time can be saved.
All counterpoints go to the expense of the low price and small size.
