Good and affordable

These stones work very well. They let in a lot of air. There are no ups and downs, which is weird. Everything Vivosun is worth for the value it offers at the advertised prices

Pros
  • Decent performance
Cons
  • Empty

Not a product I would like

I won't complain about the weight of the stone but the way the bubbles come out of the TOP instead of the stone makes me think about it Product. not quality. Watch the video before you buy air stones

Pros
  • Great price
Cons
  • Good but not great

Lots of bubbles

These air stones produce a very large number of bubbles. I'm glad I went with these stones. I use them as an oxygen cloner. I was looking for a stone that forms small, fine bubbles and they do just that. I recommend everyone to buy.

Pros
  • Comfortable to use
Cons
  • Damaged

Bad rocks work best in aquarium pumps and filters

I've tried both and they both release huge bubbles right at the base. The bubbles themselves do not come out of the stone. You might as well put an air line straight into the water because that's what it looks like. Pretty much a waste. EDIT: VIVOHOME contacted me and recently gave me a full refund.

Pros
  • Slim design
Cons
  • Available in white only

The price is too high for the item I received.

The picture shows how the product arrived at my home. Chips, missing port cover to protect from dust and foreign material on it. I'll rub it off and soak it in diluted water. There are no cracks in the base. This type of stone has served my purpose well in the past.

Pros
  • Durable surface
Cons
  • Negative gift

Total garbage vent

These vents are completely useless. They produce practically no bubbles. For the price you think you're getting a bargain but the product is terrible. I was fooled by all the other 5 star reviews but trust me don't be fooled its rubbish. You can fart in the tub and create more bubbles than these air stones. Whoever the seller is, please find another product and stop selling junk to other people.

Pros
  • Trial period for one year
Cons
  • Requires base

All air from end of fitting Like other reviews say

All air comes from end of fitting like many other reviews say. I haven't read all the reviews, I've only seen that the overall rating was good, but obviously the quality varies significantly and they look exactly like the photos others have posted with all the bubbles coming out of the adjustment. I soaked them for hours before using them and tried everything I knew but they should just work, they don't. I can still return them. I used a 40 gallon aquarium pump for a rock.

Pros
  • Best
Cons
  • Packaging ugly
