Review on Seeutek Commercial Adjustable Airstones Hydroponic by Allison Taylor

Great for blowing air! I was totally happy with it - strong flow and quiet - was able to install it under my desk on two strips of double sided tape and run my air line to my laser engraver with no flow loss! I use a 1/4" ID air line instead of a supplied 3/16" diameter line as I find it more restrictive than I need (I also used a 3D printed expansion chamber instead of the supplied nozzle/camera) - if If you plan to use this with your laser, this is a solid choice, and there are plenty of parts to choose from (purchased or free 3D printed materials) to ensure you can do air support with your particular brand of laser - but it has a lot of that river, is nice and compact for a common space issue - 10/10 winner for me!
