In the past it was limited and decent. Now it's improved considerably and imo it's as good as utorrent though utorrent has a lil more features though Halite is open source while utorrent is closed. Its also highly portable.

Its good works well at checking your files and verifies them but I have to integrate into the r-click menu in order to use it. I would be great if it was more portable.
