I chose this item going on reviews and price, and I'm not disappointed. It's not a huge lava lamp, but its adequate. As someone previously commented, once it warms up you do get 5 + wax bubbles floating about so it has good variation. It was working well within a couple of hours, but we are mid summer so the wax isn't very cold, this may change during the winter months. The lamp comes in separate bits in the box, a base with cable with plug attached (not massively long but adequate), the glass bottle containing the wax and a cup like cap that sits on top. I would advise knowing where you would put this before buying as once it's switched on you would have trouble moving it safely, without cooling it down again. Also, little fingers or bumps on tables could cause it to topple. I'm fully aware this is not a toy, although it was bought for a 9 year old. Just treat it with respect and it will give hours of viewing pleasure!
