Review on 🐠 VIVOSUN Air Stone: 2PCS 4 X 2 Inch Large Air Stone for Aquarium and Hydroponics - Boost Your Pump's Performance! by Lisa Vogt

Not as good as I thought. There aren't many bubbles. Most of the air escapes from the joint seals. One of them looks like the connector could snap at the slightest pressure. I was really excited about these based on the reviews but now I'm disappointed. I need them to replace inch and foot lengths in my hydroponic strawberry culture. At least my old ones still work! This is definitely not an improvement. Haven't decided yet whether to return it or not. If they improve by tomorrow I'll save them and update the rating.
