Awesome product, produces a nice small bubbles and its weighted. Very happy with my purchase.
The weight is pretty substantial for their size, they seem built to last, and shipment was fast!
WOW! Such a cool product! Nice open air stone with replaceable diffusers! Works great in he medium size Aquarium Co-Op sponge filter 👍
Best air stone ever! I now have 3 and all are great!
Love these air stones. Really puts out the bubbles.
