i would like to dedicate this item to my old water turtle whom we shall call H. his aquarium was never as clean as i hoped it would be, and this would really have improved his life. RIP H.

Pros:

• since you can bookmark locations and presumably have better viewing angles, you can arrange the plants and rocks in more creative ways (than you would have done if ease of cleaning and visibility were the main concerns)
• makes it easy to spot debris that needs to be cleaned

Cons:

• would be even better if it could siphon dirty water out and clean water in
