How true is the claim "silent operation""?

With no moving parts, it is totally quiet in either of the 3 modes. Have used one for the last 17 years (same, but different brand) on our 26ft. boat. Great when you don't have shore power and don't want to eat up a battery (which they do - a deep cycle battery will only last one day without charging. I use a 1 1/2 gal.( 8lb.) tank mounted up on our bridge. These units will consume .5 lbs. of propane every 24 hrs. Thus, the 8 lb. tank will last 16 straight days. A 20 lb. tank (5 gal) will last up to 40 days.

It is very true, there is no noise at all in any mode of operation. It is a cooler just like the one you find in a RV except it doesn't require any electrical control voltage to run in the propane mode.

I listened carefully and heard only the faintest click or two going into full invert. Never notice before and do not , in my case, think it is anything of concern. The mechanism is still extremely smooth and quiet. Make sure the device is set for the height of the person using it.

It is absolutely silent. I am not sure it is worth the cost. I have had it for 2 weeks and haven't noticed much difference.

Effectively no, in a silent room you can hear a minor electrical noise from the UV lights, but nothing that spooks deer.

Yes, it is really silent. I use it in an apartment building and my neighbors don't complain!

Yes. It is quiet but not soundless. If you want total silence, you will be disappointed.

I don't personally own the quiet edition, but at idle, they performance edition (I'm using 2x in push-pull) is inaudible. At max RPM, they are still much quieter than 2 Radeon 7970s in crossfire.

No. Silence. They are great monitors until they break after about a year. Seems to never fail. Purchased about 4 of them. Good luck

It's makes the sound of perhaps "light air flow." I don't think it will disturb anyone. It's not completely silent but the sound is "soft."

There is a significant amount of noise during operation, yes--particularly on the higher settings. This is in fact he reason I purchased this model over silent ones. Not only do I have several pets in my house, but I also need white noise in the background while I am sleeping, and this fit the bill for me. If you are looking for quiet operation, you'll probably want to consider another product.

it is nearly silent. since mine is attached to my keys, i only have ever heard my keys when i pick up the pill holder. but to test it i put only one pill in there, held all my keys still, and gave the pill holder a vigorous shaking. i think the only reason i could even hear it was because i was listening for it! hope that helps.

Actually, no. It's quiet silent. I was surprised to hear it. I thought it would be way more noisy.

No. Completely transparent operation from what I've seen on digital files (Apple TV) as well as Blu Ray.

Hi Chris, As far as I can tell there is no silent setting, but I've had success by just turning the radio/sound effects volume to zero. The light comes on but no sound is emitted.Bob

It certainly isn't silent - mechanical switches make noise. I'm about 70 years old and my hearing is waning a bit, but I can hear the keys. I'd say they are in the range of 6 on your scale with my hearing.

Yes, it does cover the silence but so what I did was turned it on from settings so I can access the silence button from the touch screen. Go to Settings, General , accessibility then assistive touch and push it on instead of off. From there, I was able to turn use my silence button

not at all, I didn't hear any noise in fact. (note: it's a open workplace not a private room)
