Dawn, I don't much about the Enviro, but with only one head & presumably only one removable cover(?), I think I'd take it back & apply the money towards another brand that gives you more options. If you'd like a link for a deal on Sharp products, let me know; I get regular mailings for special offers & am sure I have one til the end of the month. You can always do a Google Search & it should take you to the Sharp company site. I'm new to this site & not used to how all this works (frequency, notifications, etc). I'm a quilter (machine piece & hand quilt w/ a weekly group), machine embroiderer & sometimes do home decor projects & alterations (more & more reluctant!).
