It is very easy to disassemble and not really difficult to assemble. But not for everyone.
I call myself a more qualified techie. Description I have not read.
What really bothers me:
The transponder slips in the thing back and forth. Since the rubber is missing. After a bit of tinkering he holds.
The battery contacts are missing. This can but really no more than 10 cents, which would have made it.
Otherwise, I'll see if everything works.
