I purchased the bubble lamp for my grandsons' bedroom which I have newly decorated in a 'seaside' theme. I was pleased with the delivery time, took only a couple of days. Just to let you know a few things that it doesnt tell you on the site. Firstly, the water you use has to be distilled water. Tap water has too many impurities which could hinder the functioning of the motor, so the manufacturer states, and invalidate the guarantee, so it was off to the shops to find distilled water.(Takes approx 7 litres) Secondly, there are only 8 fish included with the tube, and I think for the size there should be more fish. So it was back on the net looking for extra fish, which I found quite easily. I read the 2 previous reviews,and regarding the first review, the fish do tend to stay at the top of the tube to begin with, but after a few minutes being switched on, they gradually drop down and beginning swimming about so it does function well and looks good as it goes through the sequence of light changing. Lastly, there is a bit of noise from the motor, whether this because it is on a wooden floor and not carpet, I dont know. Having said all that, I think I made a good purchase and my 2 grandchildren are delighted with it! Makes them want to sleepover more often!!
