Really? Mine (Box 2 prime 9) is going great after close to two years of near constant use. It needed a couple of adjustment tweaks soon after installation and then again after a fair bit of use, but I expect that with any drivetrain. My husband has microshift advent (9 speed) on his commuter and can't fault that either.
@safreek MTB direct have this on special too:

A couple of things to note:
The Box groupset you are looking at is single shift.
The Microshift groupset pictured above doesn't come with a chain. You need to buy one separately.
