Very quiet. OFF flag is dependent on rotor speed, not power application... be prepared for a short wait until the rotor spins up and the flag disappears.

Unfortunately I’ve to send it back. During run-up the red flag came out…let’s say few minutes of use! Pity the Rc.Allen I had formed just fine for 22 years! Boring I’ve to dismantle and send it back! AT

In stock, was able to pick it up the day I ordered it. Hope it lasts longer than the unit it replaced.
