Review on 🌿 Stainless Steel Metal Lily Pipe Inflow Outflow for Aquarium Planted Tank by JARDLI by David Amarelo

These whistles are made of very high quality steel. The polished finish is classy and the included suction cups are durable. My only downside is the actual curvature of the exhaust pipe. The spout is designed to be submerged in water and the angled cut creates a voice that pulls down from the surface, which they do well. The problem is how much the pipe bends before it goes out. This requires a much lower level or pipe lift to oxygenate the water. This may or may not be intentional, but I had to see it. Also, they still work very well, which is why I gave it 5 stars.
