I use this model for a year and I am very satisfied as the point of view quality / price ratio to use. It is clear that a professional of his choice will show on a more powerful model, but the fans (DJ, occasional managers, etc..) Not an intensive use of this accessory should be satisfied. It should also compare the cost of the lamp!
In short, I strongly recommend that all users Lyre amateur (or semi-pro) who do not have deep pockets and can return their purchase by benefits and regular pay (voluntary = ex-volunteers).
