Not bad but if you're using a hi-res screen on a Windows platform, it is really awful to use due to font rendering issues. I use it on an older desktop machine in my home as it's unusable on my work PC - a Lenovo Yoga 2 Pro running Win 8.1.Win 10 might improve things a little, but it's time software authors get with the world off hi-res monitors as they become more common.
