As against the product .... worth more than the price. short and silent running, I wanted a low profile keyboard so I would say it's going it's acceptable. As against the light .... cyan and green are super bright and blue .... a little light and brightness levels for all coleurs there are plenty of places it's dark or see no lighting ... the price that the cost of the day led frankly today can do better ..... for the price it goes, correct product overall.
