I pre-ordered this neat lamp because I have been a fan of TETRIS since before I could walk! This light is great, and is appropriately priced for what you get. The packaging was very protective, and the box arrived inside a shipping box which means the actual product box is pristine for gift-giving. Each piece is wrapped in a protective baggie.
The pieces are plastic with thin metal borders. I was under the impression the pieces had magnets and would "stick" together when they stacked - this is not the case. When you put the lamp together, in whatever shape you choose - do so on a level surface that will not be approached by pets or children. The pieces are not magnetic and do not stay together on their own, they just require a lot of gravity in the area they'll reside. (Alternatively, hold the "down" on the D-pad to keep the pieces connected.)
The blue block is the base. It will receive the power, so you must like blue since it will always be on whenever your lamp is. There is an on/off switch on the back of the blue brick so you needn't unplug it or hunt for a cord switch every time you want it off. All you need to do to turn the others on is touch them to the blue base when it is switched on and plugged in. The colors are pretty vibrant, but the light behind them is not a "general glow;" it has a focal point as most LED lamps tend to have. The lamp should not be used for task lighting, since it is not bright enough. It would make a decent ambient, mood light, or to have on while watching TV or playing TETRIS so you don't get a headache.
All in all, this is a great light! I bought another for myself so now my whole family can bask in the glow of old fashioned video games without actually playing.
Edit: I purchased this light when it was around 45 dollars, but since the review went live the price has changed. I would not buy this lamp for the current price of 80 dollars unless novelty lamps is your "thing" that you are super into. If I had spent that kind of money, I would be disappointed both in the fact that it can be found much cheaper elsewhere and that the construction doesn't live up to that price. Also, I have amended the educational rating of the lamp, since I had to explain conduction to someone who asked how it powers the other lights. I suppose... that oughta be filed under educational, too, oughtn't it?
