Works Loudly:
This air pump works but it pretty regularly starts making a very loud noise as if it is revving up an unseen engine before the green flag comes down. Unfortunately, it won't stop making this noise until you pick it up, look it over for some hint about why the air pump sounds like an experimental music festival, and then put it back down. Even if you put it in the exact same spot, the Rena Air 200 seems satisfied because it will return to the quiet hum...for a half-hour or so. I gave it to Goodwill who will hopefully help it find use some place out of ear shot.

Not what is represented or I have a bad one. I don't know which. Should have returned this one but didn't.
