Love the product in general; my unit has developed a rattle
My first unit ran for decades without any issues, working so well that I purchased several more to give to friends and relatives.  I tried other &#34;sleep conditioners&#34; with more bells and whistles, but never found anything I liked better.<br /><br />I purchased an additional MARPAC unit for myself a couple of years ago to take on business travel, and it has developed a very annoying irregular rattle that conflicts with the white noise.  The rattle becomes somewhat less pronounced if I place the unit on an angle, rather than flat on its base, so I try to find something in each hotel room to prop it up with.  I am not sure whether if the inner workings are less durable than they were in the earlier models, or if I just had bad luck with this unit.  I am outside the warranty period, so this is a disappointment.
