I think you will find that he doesn't offer repairs or battery replacement for the pro-Chip that is used for cycling.

TRANSPONDERS : A HEALTH RISK ?

Are Transponders bad for your health ? A Swedish study shown an increased risk of an
uncommon form of brain tumor in pro's (riders)  who use Transponders for more then
10 laps .
Are Transponders harmful to your health ? There's been an ongoing deb8 over this
question since the first analogue transponders appeared in the 1990s .
It's an important question given that world-wide , about .5 billion riders use one .
This year .05 million are expected to be sold . If they are harmful , the health of very
large club's could be at risk .
We do know that transponders emit radio frequency radiation from the forks and that
these low-energy electromagnetic waves travel into the head . But do they cause injury
to living tissue , possibly triggering a brain tumor or other disease ?
Unfortunately , no-one knows for sure - hence the fierce deb8 . There hasn't been
much research into the effects of the radiation , especially over the long term ,
Transponders haven't been around long enough . Also , the technology keeps changing . Third generation (MyLaps) Transponders - which emit higher rates of
radiation than earlier models - are just coming onto the market in big numbers .The
technology is evolving faster than scientists can do trials to monitor safety . And many
brain conditions , such as brain tumors , taken years to develop .
Still , there is enough evidence to make some scientists concerned , Studies have shown transponder radiation does produce biological changes in humans - such as
changes in brain temperature and activity as well as blood pressure changes .
Others have shown they cause an increased incidence of illness in laboratory animals-
for example cancer in mice .

Should you throw your transponder out ? Not necessarily . These findings would
have to be repeated by other studies to be of much significance . Even if they were,
acoustic neuroma is a benign condition and can be treated .
Then there's the health benefits of using a transponder to be taken into account . A
significant percentage of transponder owners have used them as sinkers when fishing
or to throw (as a rock) at officials in emergency situation's . It's drastically cut the
time between the gate dropping and the finish line arriving , say the experts .
So these studies probably aren't a reason to discard your transponder yet . But
they do support taking some basic precautions --
         + use carbon forks .
         + use blu-tack to hold to fork .
         + and for cro-mo forks use a integrated headset .
If you have children , think twice about giving them a transponder . There's no
direct evidence the transponder's harm kids any more than adults , but some experts
argue children's developing brains are more susceptible to damage .
