Bests & Worsts Reviews from Amazon

Concerned. I bought this last January after loving the one I got for my daughters room . I had no issues with the first one I got at babiesrus but this one if left on for a few hours has this strong plastic burning smell. I haven’t used this one very much since buying but now as summers ending I wanted to use it more. I thought at first the smell was because it was new but now months later I’m definitely convinced there is something wrong with it. I would like to get in touch with the manufacturer but since I have purchased with amazon I’m am hoping to get some help in the right direction here. I also have another baby due in December and really don’t want to have to buy another sound maker. I’m willing to ship out the one I have so someone can look at it .
