We have had one for years, a real work horse-with things constantly going in & out on it. You do hear it make a little whir when it starts, but not annoying in my opinion & I sit near it. There has been a problem now & the sending to a particular office but they have problems with other offices sending to them whether on Sure West lines, Comcast phone lines, or others, all with other faxes, so I do not think it is a problem with our Brother 2820. The only 2 things I feel it misses is being able to set the re-dial function for more than one re-try in 5 minutes, which is often inadequate, or for a longer duration between tries, and it is cumbersome to change the setting from whether you want a receipt printed for your transmission or not- a one-button change would be nice, to save paper. I haven't seen any other machine that sounds any better or has better reviews- particularly for $ so I will be buying another. I can not rate service- any problems I had were solved in forums- like the machine sometimes saying it needed new drum when it did not- simple re-set to do, but this should be in the manual as it happens every so often.
