First thing I noticed when opening the package was how heavy the keyboard was. It feels very sturdy and the keys function well for the most part. It does take a little bit to get used to them, likely because of the how little you have to push the letter down.
However, I can't give this keyboard and mouse combo a higher rating than 2 stars because the mouse was absolutely terrible. It's very lightweight, it feels cheap, and the overall shape is awkward to grip. The functionality has also been subpar, especially the vertical scrolling wheel. It is not smooth at all and gave me a headache because of how choppy the movement was as I was reading. I've tried to adjust my mouse settings at first, but nothing changed the choppiness; it seems to actually be an issue with the mouse wheel. Compared to the microsoft and dell wireless keyboard+mouse I've purchased in the past, I would have to say this one by Amazon is the worst of the bunch.
Overall, I'm very unimpressed and will likely be ordering from another manufacture in the future.
