very authentic and realistic for the price you can buy this. Unfortunately, it does not come with AC/dc adapter but you can find one almost everywhere. It also works on battery.
I picked this item up to create a more relaxing environment in my living room and I really liked the price. When I got the item, it was very loud, it didn't come with a power supply (so I had to use batteries) and the LED lights did not turn on. I ended up returning it.
