Review on 🌱 Nano Glass CO2 Diffuser for Plant Aquarium Fish Tank - Aitao Bulk Pack of 3 with Suction Cup by Diane Collins

Of the 3 diffusers I received only 1 worked. The first one I tried had a hole where a long, curved tube meets a large cylinder. The second broke in the same place when I tried to connect the hose to the diffuser. I must have been lucky with the third one because it actually worked. Also, the diffusers look completely different from the picture, and differ in size in shape. They are much longer and larger than the photo and the fact that all three diffusers were different sizes and two of them broke shows how poor (or nonexistent) their quality control is. These diffusers are shipped directly from China and it takes a long time to deliver. The long delivery didn't really bother me - it would have been worth it if I actually got three qualitatively decent working diffusers.
