    This is a great science example to demonstrate magnetism, electricity, solar power, and the interaction of all of these together to create power. It looks professional and quite stylish. The actual picture is close but not exactly like the real thing. The suspension magnets are a different size but that is all. The build quality is good. The adhesive tape holding the solar panels to the hex-shaped plate looks like it may loosen with heat (sun), so I will have to see if it needs extra glue over time.

    Good looking Black rod received - not as shown in photo magnet and solar panel not in perfect condition one side of magnetic on rod loose and came off - I have to re-glue it. Overall it's acceptable.

    Заказ только получил. Товар полностью соответствует описанию и фотографиям (соврал... боковая часть ротора непрозрачна :) Упакован очень качественно. Да, немного нуждается в центровке. Будет солнышко на дворе -- проверим работу.

    Very cute. Even without a sunny window (in Arizona houses tend to avoid south facing windows) I just point a flashlight at it and with it's magnetic levitation mount it spin for a long long time. Makes a fascinating entertaining demonstration just like a crookes radiometer..
