Amazing, except for the battery

This keyboard fulfilled everything, only problem was the battery life.

It's really good

I would highly recommend this one if you're looking for a mechanical keyboard within 40$. But if you can spend more, I would suggest to find one with better switches because keyboards with a price of 70$ usually have switches that have a very soft and satisfying feel at every key stroke. This one has a bit of a rough texture to keystroke but still pretty good at 40$.
