Must say while I was quite impressed with the Penguin window itself,
the manner in which this product was presented and marketed is quite
misleading, manipulative and downright aggravating! Not to mention
that it is extremely overpriced (four times our quote from Home Depot)
and complete with bogus "science" experiments, phony "suddenly
discovered" discounts (which continued to be offered even after we had
signed with another company!), and high sales pressure. By the time we
asked this salesman to leave our house, we would not have bought a
cup of coffee from him, we were so annoyed and had no confidence in
anything, including the supposed quality of the window.
Wise up Penguin. You've got a decent product but you need to stop
treating customers like they are idiots and let the product market
itself at a decent bottom line price!
