If you don't own Apex, this is my favorite. Rock-solid dependable, has built-in rechargeable batteries that last 6-12 months on one charge. Use a piece of tape across the adjuster so you don't accidentally bump the setting when refilling. Other than that, it's superb.
I've used Eheim, Oase and at least 2-3 others of various designs. None of them come close to the Zacro.
