Is this adapter fairly noisy or is mine defective?

The right angle drive involves changing the direction of energy which involves gears and in the case of this device, flexible cables. This accessory will generate noise due to those facts and isn't a problem unless you experience lowered RPM or "dragging" which indicates binding. Noise is normal, greatly reduced motor performance isn't. This adapter should only be used in the case of restricted space or ergonomics.

I had one that was very noisy and would not even run at all speeds so I contacted Dremel. They sent me another and it was still a little noisy, they are known for that, but it was much better and I am still using it.

No, I had no problems with mine. Could there be an adapter that would make your work? I really like mine.

I don't think so. It's fairly loud. Admittedly I did not have mine very long. It tested at least one known good power supply ( brand new, about a week old) as bad. Don't think it's a great product. Returned mine.

Mine only makes the noise for a few seconds when I first plug it in. Other than that it is quiet for me.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

No I have not noticed any strange noise in mine. Sounds like yours is defective.

They're not noisy for me. Is it the lights themselves, or the power supply you're using?

Yes it is much noisier than a typical internal device. I suspect it has something to do with its compact size

All of what has already been said, AND, the headphone link is very noisy. Mine is anyway. Buzzes...hums... Same with two different inputs, two different power sources, no matter where it is placed. It's not an enviromentally induced noise...it's the converter.

It seems, based on the answers here, that it is hit or miss. I ordered two of these, but they came with no adapters so I have to return them both.

If the adapter didn't come with the unit you're SOL. Go back to the store where you bought it and return it or maybe you can find another unit on ebay or Craigs list. I don't think much of the unit anyway.

I also have the noise coming from the unit. HDMI Passthrough is "ON". Looks like it is a "feature" of a cheap transformer that is installed inside the unit...

I would check that all connections are not loose. It sounds like you have the power usb cable plugged in but check it's connection as well. I'd suggest contacting the company if you have further problems.My monitor has worked flawless since installing the adapter. Sorry to hear you are having issues.

You should check to see if they're are any appliances that might be causing interference or "noise". I had a similar problem where the speed was slow, but I found out that in other locations of my house the performance was much better. After I poked around for a bit, I found out that after unplugging my mp3 recharge adapter the speed increased dramatically. It may be a bit inconvenient, but you have to try unplugging devices that you suspect may be causing the problem and plug them elsewhere. This could be the only way.

I'm not sure I can answer your question. My adapter has performed exactly as advertised. I purchased 2 of these about 2 months ago and I have not had any problems.

In addition to the previous answer about an adapter, I can tell you that it's not a good hand-held mike. It's very susceptible to handling noise.

you may want to check if the hissing comes from the device base or the power adaptor, make sure the device is off.
