I am happy with my Proneb Max. I’d bought a small cheap one because it was the only option to buy immediately. It was ok when I just used albuterol, but was slow and when I added saline, the time it took was prohibitive and I ordered the pro-neb max..
It has a higher psi so faster. It is louder (65-67 I think, so I wear headphones for noise.

If you use search by heading feature
(Magnifying glass) by heading, and search for nebulizer, you’ll find other options and opinions.
