Question: What's going on here, does the light uses batteries or electric?
Document: It was a replacement for my granddaughter and it was perfect gift. She uses it as a night light everyday .
this is a great night light. my son loves going to sleep watching the fish. i would recommend this as a night light for all little ones!
I purchased this item for my wife who is in assisted living. She enjoys watching it, especially in the evenings as she is going to sleep. Much better than just a night light.
My daughter really wanted this after seeing it in her audiologist's office. Sadly, when we plugged it in, the light came on but it didn't turn. The return was easy enough and I received a full refund. We're going to look around for an alternative.
We purchased this for our grandson to use in his bedroom as a night light. They have recalled several models but not our granson's model. We are to scared to use it. His life is not something we are going to gamble on. We're stuck with this Animated Marine lamp and to scared to use it. DO NOT BUY!! I would be Leary buying Discovery toy again.Discovery Kids Jelly Fish Lamp
My sons loved this little night light aquarium. It worked just as well as the Discovery one they had before. It was really quiet and put out just enough light. I bought it in January 2013 and now (Aug 2013) it suddenly stopped working. Just like other reviewer mentioned, I opened the aquarium to change the bulb (CFL), but fount it to be permanently installed. So now it's going into the trash.
My wife uses this item in her classroom and hew kids just love looking at it. Nice price for this item.
Bought for my son. He uses it as a nightlight. Item was exactly as described. Great price shipped quickly  loved it
This is a very cute little light and it's very relaxing to watch the fish swim around. However, after about 10-15 minutes of running the tank starts making some kind of grinding noise! I'm not sure what's wrong with it, but that noise isn't too pleasant. Other than that I enjoy it!
Got it for my granddaughter for Christmas she really liked it all the fishesNowater awesome and no batteries even better
