Review on 🐠 JARDLI Aquarium Air Bubbler Glass Cup - Bubble Sputtering Protector by Anna Lee

Edit: On my first attempt to clean the item it broke and cut my hand quite badly. When I wanted to exchange the item again, the price was increased. I'm done with this product. I am reducing my rating to 2 stars. It's cool in theory, but the execution really left a lot to be desired. **Something worth mentioning, the replacement they sent me for the original which arrived broken also took almost 3 weeks to get here. The straw in the cup arrived broken but I'm going through the replacement process now. Hopefully round 2 will be a little better. As mentioned in other reviews, the suction cup mounts are located quite high on the mug itself. I hope they are placed a bit lower in future versions. While I haven't installed a broken block on my tank, I think I need to lower the water level in my rimless tank a bit so I can place the cup properly. One of the two included Airstones also arrived with quite a bit of dirt already stuck to it. It might come loose if hit in the tank, although I'm not sure. However, it's worth noting that Jardli is the only manufacturer of this product available (from what I've seen), so there aren't many options. This device is also not required.
