I love the fact that I can look at it from above and have a clear view without any water ripples.
I got it around the Christmas season, so it was on sale for $99.99 at Petco and they send me coupons. So I used a 10% off coupon along with the sale, I ended up getting it for $98 and some cents. I actually here that Petco and Petsmart usually have the Edge for sale regularly for $100.
