Loud whine makes in unusable in a home office
928798
I can not tolerate the somewhat high pitched whine.  It may be fine in a space where there is a lot of other noises, but not in a home office.  It does work well as a mini desk fan though.  Just noisy.

UPDATE:  The company was outstanding in rectifying my complaint and sent out a replacement.  I could not be happier.

When I plug it in it screeches so loud and has so much static on it, we can't hear. I tried to return it but I have missed the deadline for returning.

Do not buy this if you have any sensitivity to noise. It's unbearable and so annoying. I tried to return, but they were going to charge me almost as much as I paid for the pad. So disappointed.

This product works well (pretty simple technology) but the alarm IS SO LOUD. It is such an annoying, shrill sound that wakes up everyone in the house.

Although it does seem to have great sound quality under ideal conditions, as other reviewers have mentioned, it it quite susceptible to interference.  From the first time I tried it, there was a high-pitched whine in my recordings.  I spent over 2 hours shutting down computers, unlpugging electronic devices, etc., to try and find the source of the interference.  It turned out to be the overhead fluorescent lights in my office.  Once I turned them off, it no longer recorded the background whining noise.  Just something to be aware of if you have fluorescent lights in the room where you'll be using it.

The products came shipped in a shoddy cardboard box with a few pieces of newspaper thrown in for insulation (not nearly enough to protect such a delicate piece of machinery). The wire was already plugged into the interface and the CD case was placed on top of it. I needed to re-install the drivers even though I already owned and used this same exact interface with my rig before in order for it to work. After a while, I started to notice an extremely high pitched noise emanating from the device.  I am positive that the noise is coming from the device and not something else because it is only audible when the device is plugged into my computer.  I tried different wires, re-installing the drivers again to no avail. The noise is extremely annoying and makes producing a headache, I can't stand to be in my studio with it running for more than a few minutes before I start to contemplate suicide.

You have to scream to be heard.  Tried adjusting all the setting in windows and nothing.  You get what you pay for.

Works great, but when nothing else is on in the house (like the TV) it's rather loud and annoying.

Product worked as advertised but there was terrible feedback through the device. Unusable because of the whining sound.

Makes very loud whining / buzzing noise when console is powered on. Also interferes with nearby electronics causing them to malfunction. Returning.
