Wow, I hope your results are better than those of the reviewers. You never know as you said some might have installed them in the bathroom, or perhaps installed them incorrectly. I take reviews with a grain of salt these days. People seem really quick to jump online and blast negative reviews, but I've yet to see one come back and say they made a mistake. Hopefully since they're in home improvement stores, they'll be decent quality, and it sounds as if @Holly Saunders has had good luck with hers.
