I use the revosweep for over two years.
dipstick purchased in addition to a Cyclops jbl system (to turn a mushroom of 250W).
The special feature I like most is the weight (light), it n'chauffe not (it is sometimes turned on 12 hours without any problems), although it would in time, it responds well to music.
Following is an entry-level product, so only it does not cover a song, it breaks no bricks (some say that this kind of effect done Girlanda of Christmas is not false, but good and globo lyre is not the same price). They advertise on the box equivalent to a yield of 250 w hallogène is exaggerated (it flash unless my mushroom of 250W).
good value for money.
j'referais this choice without worry ...
