It's literally crap!

Poolife
Here we have Poolife, a company that sells pool cleaning products.
Seen anything wrong yet? Have you parsed the named as POO LIFE thanks to a missing L?

This especially hurts for such a product since the name now has a negative connotation (you don't want 'crap' in your pool!) and many will read it like the way described above. It certainly wouldn't hurt to double up on the L in the name...
