I like the sounds. Only thing is it said it took batteries and could plug in, but there isn't a slot for batteries & instructions don't list batteriesSuper easy to use with lots of sound options and it holds a charge for a really long time. Couldn’t ask for a better portable option.Yes, all nice and great for travel, has this cute light and nice volume. BUT:-I dont use it much for travel so that feature means little to me.- it has only 3 melodies that simply repeat itself over and over.- it has only 3 background /white noises and none of them are the rain or rushing water which are the only ones that I use.- and the worse, once you charge it, it lasts around 1 hour, hour and a half tops. Its a pain to be charging it so often. I much rather use batteries and forget about it for weeks.I intended to use this for every baby nap every bedtime and it's more inconvenient than helpful.Works well, Like that it has a nightlight Baby friendly shape & face. My grandson seems to like it & watches it as he falls asleep. Would like some different songs. a couple of the sound effects are a little odd but we use the music now that he's not a newborn. Overall happy with the purchase, good value for the money & easy to use. I really like that it is rechargeable & does not have to have new batteries all the time. I sometimes have it set to" on " so it does not shut off & if I forget to turn it off I don't have to get new batteries just recharge it. Selection of setting is nice.I bought this for my second child having been around the block once before, I knew I needed a sound machine to drown out sound for sleeping. He is 5 months now and he ONLY sleeps with this in his crib or next to him! I love that when I plug it in, it doesn't take long to charge and the one charge lasts 3 days! Obviously it's not on the entire 3 days but I don't have to plug it back in for 3 days which I think is great! This is by far the best thing I bought for him! He sleeps through the night and I can thank this little sound machine for help with that!I got this a couple of days ago and I am loving it already!I love the fact that you do not need batteries and it has many optionsLike : Night light6 or more different sounds, my favorite is the fan noise and or the shuuuu option hahait helps to block noises from the house and it helps my baby stayed asleep. Maybe not all babies like this but if you are looking for a white noise machine that's good for in the house or to go and its economic then this is the one!AMAZING! I’ve literally never wrote one Amazon review in my life. My daughter loved the “shhhh” video on YouTube and would only fall asleep to that noise. I would put it on my cell phone but that left me without my phone until she fell asleep. Also, any of our family that watched her would be without their phone while she napped.This is a game changer!!What sold me on this one above all others:-USB charging (no batteries-HUGE plus!)-the options to play 30, 60 or continuous-night light option-easy for putting it on stroller or crib & small enough to pack in her diaper bagSeriously. Since having my daughter 4 months ago, this is THE BEST money spent!Love it. Would've died without it. My daughter is currently 19 months old, and has used this every single day since we bought it not long after she was born. We keep it in her room and use it every night, we take it with us when we leave if she's going to nap somewhere and it really helps block out any extra noise. I'm definitely guilty of not being loud enough with my daughter while she slept when she was younger so if my mom is visiting and being a little loud it helps block that out so she can focus on sleeping rather than focused on what her GiGi and mommy are talking out.
