The keyboard is made out of cheap plastic and it looks like a child's toy to be fair. The lights have a fixed rainbow color and you can only turn it on or of. The lights are not so bad to be fair and look pretty good, they are not too intense and not too dim, and the best way to use the keyboard is to keep them on all the time, because, if you turn them off, the keys are barely visible, the white letters are washed out. One annoying thing about the lights is the fact that whenever you turn on your pc, after you turn it off, the lights won't come on automatically, so you will have to turn them on yourself, manually, and I find this annoying.
The keys are membrane and are soft to touch, they feel quite good considering that.
The mouse is HUGE. I have a big hand and this mouse is big even for my hand.
It has a nice RGB cycle and it doesn't feel that bad once you get used with how big this is.
It has plenty of buttons to use in games and a few DPI presets that you can change by pressing the DPI button. It is an ok mouse, considering the price. (it also has a nice brided cable)
The mousepad has decent quality, flexible and with a rubbery base. The problem is that it is too small, it's surface is too small, so, whenever you use it, you will hit its edges with the mouse, and the edged are a bit lifted than the surface, so that can get pretty annoying as well.
All in all, I would only recommend this bundle if you are on a tight budget. It can do the job, but it feels really cheap and it is not so pleasant to use.
