Defective Good, valent impression, but after repeated use

I bought the remote release in December 2010 and in the meantime used about 10 times. He has worked perfectly.
After I but almost every time needed new batteries in the first time (it is also energy, because non-existent
Off switch used), I have these removed after completion of the work from the receiver and transmitter.
At the receiver with 2 AAA batteries very easy. The transmitter with the button battery insertion and gutting is a
annoying fumbling (long fingernails or a mini screwdriver here are absolutely necessary). It must now also
are being watched like hell that the very filigree metal nose which manufactures both to hold, as well as contact with the button cell,
is not bent.
And then it happened, what actually had to happen sometime. When replacing the button cell, the metal nose is broken
and thus the remote release is now unusable.

Per
Highly reliable operation
Illustrated instructions in English / multilingual Quick Start Guide
standard cables included here

Contra
Changing the battery in the transmitter is not easy and involves risk of damage
No off-switch, thus also power consumption outside of the insert
Excessive power consumption of batteries in use

Recommendation:
Because it happened to me already a couple of times that I stood there with empty batteries, I still have a cable release it.
Goes in certain situations, but in animal shooting outdoors is an absolute no-go.
The exchange of coin cell I have always done in daylight, or in rooms. With warm fingers
does it even reasonably, but outside, depending on weather conditions is it more critical.

Conclusion:
Good functioning part, however, is irreparable with weaknesses and thus lead to the devaluation.
