Review on MagTool Aquarium Circulation Programmed Patterns by Beth Pujol

Great design. Small and unobtrusive, quiet. Fantastic river for its size. Comes with three grilles so you can have a wide, medium or jet flow path. It's really nice that there are also cable accessories - suction cups and self-adhesive cable clips. In addition to well thought-out design. The cable length is great. Allows the unit to be hung under the aquarium stand on a small hanger (included) but is easy to remove from the hanger and pull out to adjust flow settings. The control box has a small blue light that shows it's connected to Bluetooth, a small red light that flashes when it's receiving a Bluetooth signal, and a larger blue light in the center that shows the strength of the stream. It's so nice to be able to increase or decrease the power so easily to adjust the amperage! And you can easily switch between flow and wave strength settings manually if you want. It's good if you're doing repairs but don't have a phone handy. The application is simple - connects immediately. Also has a timer controller function! Even when the device is closed in the aquarium stand, Bluetooth works reliably. After a power failure, it returns to its last setting. The only downside, depending on your application, is that the suction cup design that secures the device to the internal magnet can limit the angle at which you point it. If all the suction cups are firmly attached to the back of the device, you can only get an angle of about 20 degrees up or 20 degrees down. If you tilt it down steeper, not all the suction cups are seated correctly. You can also get a bigger angle, it just won't be fixed as securely. Very happy with this product!
