The positive characteristics have already been mentioned enough. Here are my criticisms: - There is no white color (neither cold nor warm white). The white is dyed blue. Luckily I was warned by a review. Also, I do not attach great importance to the White. - The supply to the transformer could be longer, so that the box is not "in the air" hangs with me and reaching to the ground. Likewise, the sensor cable may be slightly longer. - The Euro plug is left when removing the plug into the socket. Children in the home not as low.
