I have not conducted any scientific studies, but I can report my
experience.
We have sold several thousand of these devices since 2001 for the
purpose of getting rid of bats from our customer's house and
barns. We only have three years of statistics indicating
the amount of customers that have solved their bat problem or
have greatly improved it.
1st column is the year of sale.
2nd column is the percent of customers that tried our
devices and were disappointed with the results.
3rd column is the percent of customers that tried our devices
and were pleased with the results.
Year...................% returned ................% kept
2005.......................7.8%.......................92.2%
2006.......................7.2%.......................92.8%
2007.......................6.9%.......................93.1%
2008.......................6.6%.......................93.4%
2009.......................6.9%.......................93.1%
2010.......................7.0%.......................93.0%
2011.......................6.8%.......................93.2%
You may have noticed the statistics for 2011 are a little better that
2005. We were selling the same device in both years,
but I just think our advise and understanding of how to use them
has improved.
Over the years I have tested many of the electronic devices for
functions and output. The unit that we sell now is a very good
unit. It is designed with "Sweeping scale technology"
an advanced ultrasonic broadcast management feature.
The bottom line is:
I make money only if you are satisfied and keep the product.
If
you are not satisfied with your purchase we will refund every dime
charged to your card. We keep nothing, no fees, no shipping, no
handling.
