Several shrimp, a ramshorn snail, and several aquaric plants approve of this product
Firstly, unrelated to this store or its products, I dislike Amazon and try to avoid ordering from it 99% of the time. I'm a dork that tries to buy from relatively local brick and mortar stores or try to make an online purchase from the later..... But gez man! Tiny airstones seemed to be actively hiding from me at my local pet supply stores lately, and so here I am! Second, I have an absurdly small tank. My <10gal air pump is literally overkill for it, so I have a valve to adjust flow to my airstone so it isn't blowing the water out of my tank rather than oxygenating it. My old airstone wasn't having a great time and long story short, the bubbles it was belching out sounded awful, and if I was annoyed by the noise it was making, I can only imagine how fed up my shrimp were with having to live with it. So, I started my hunt for a new airstone, sold my soul to Bezos, and found myself the proud new owner of a Hygger Airstone S35 (1.25"). It's only the beginning of my and my shrimps' relationship with this airstone, but our first date was better than expected. Maybe the Amazon interface is designed in a munipulative and intentionally convoluted way, maybe I was just too blinded by my conflicted emotional state in supporting a service that fails to support and empower its own employees and small, individual vendors it plagarizes from....I digress. I didn't realize how much more I was actually going to receive with my airstone purchase! A control valve, suction cups, check valve, a freaking t-connector, and a reducer on top?! All I meant to purchase was a practical airstone that would quietly blow tiny bubbles (honorable mention to the small user manual for including a tiny and adorable 'application diagram' including a supper table and Nemo) and Hygger delivered that and more! Finally and most importantly though, is that my shrimp appreciate the new air stone. They're mildly concerned about the white colour -- because algae will inevitably leave its mark on everything -- and that it wasn't the agreed upon <1" stone we discussed... but ultimately, the airstone makes up for it in adorably tiny and peaceful bubbles as advertised! A few shrimp are currently enjoying a serene bubble bath. I find myself checking to see if the airstone is actually working because it's so quiet compared to the old one. Very happy with the product so far. Tldr: So far so good. It works as advertised and I would recommend. Be ready to scrub the stone regularly as algae will easily discolour it (unless you prefer a more natural algae-chic look) and have some appropriate superglue on hand if ever the stone pops off the base.

Aquarium Saving Grace
I have a 40 gallon tall aquarium. I've had issues with it crashing and killing my fish since I've had it. Wanted to scrap the whole aquarium because of the issues thinking it's AIO design was the problem. I've added 2 sponge filters and a hob filter to the sump itself. The water is definitely well filtered and yet, despite my efforts I had another crash after a minor water change. Did not change media at the same time and I used bottled spring water. I can't trust my tap water even with prime conditioner. Saved only 4 fish from the crash out of like 20 schoolers and put them in my 10 gallon. Oddly enough my Opaline Gourami who I couldn't move due to his large size was fine. I thought he'd die but he lived and thrived, gulping air at the surface occasionally but resting comfortably in his claimed cave near the bottom. I didn't understand why my gourami remained healthy in the crashed tank while all but 4 of my school fish died until it dawned on me they're like bettas and breathe air. Despite my bubbling sponge filters, there wasn't enough oxygen especially being a tall tank. There was so little oxygen, not even my pest snails could survive. This bubbler has changed things immensely. The bubbles are very fine and make the water fizzy at the top, properly oxygenation the tall water column without introducing extra turbulence in the water that could stress my small scooling fish. This let me readd new fish to the tank and so far, they're relaxed and eating well including my bottom dwellers. Plants that were dying or melted have come back, some I don't remember planting or thought were long dead. Even my snails are back and slowly repopulating. It's quite. It pumps in a lot of air at full blast. It keeps my fish alive and well. Without this, I would've tossed the tank when my gourami would pass. I can now enjoy my tank and pray I don't have another crash

Very fine bubbles and very quiet operation.
Larger base than expected, bubbles are very fine when used with a decent volume air pump. I recommend an air pump that has adjustable outflow to tune it in to your desires. As theses bubbles are so fine, it is best for dissolving oxygen in the bubble column rather than using it to create surface agitation, as the bubbles are so gentle, they won't move a lot of water, but this also makes it very quiet. Overall works very well as a fine misting air stone in a room where noise consideration is important. Been running for 3 weeks with no issues at all.

La verdad es que si sigues las instrucciones está súper, efectivamente si puedes moderar la cantidad de burbujas que salen y sin problema. Solo tienes que comprar la manguera por separado pero cumple muy bien su función.

Great bubbler! Even running at 75% air power (I put a control valve in the tubing) the bubbles are very powerful and tiny, and it fills the water with oxygen!! I can tell my fish are very happy to have so much air to breathe now. Beautiful product! And a bigger airstone than I was expecting. It has a very heavy base and

Me parece muy bueno el tamaño para acuarios pequeños, si saca unas burbujas muy pequeñas, tendré que ir vestigar como limpiarlo
