Can be a little uncomfortable but mostly seems effective. I haven't had it long enough to see results though .

Not seeing a great improvement.  A friend told me this worked very well on her dog, so will give it a little more time.

I like it.

It seems little too weak power, but in general it works well.

This seems to do what it says.  It seems to get most the moisture out the air in our small bathroom.  It's not instant of course, but a process.  It seems to be helping decrease our mildew problem.

It works, and it seems to work well.  I haven't had it long enough to comment on longevity.
