Someone bought that exact same espresso machine for our break room at work a couple of months ago. It is already broken. Apparently it relies solely on water pressure to puncture those metal capsules, so if any of several things happen to cause the pressure to go down, you’re hosed. I’ve personally tried several things to fix it because I really enjoyed having espresso at work (even if it’s from a capsule), but haven’t managed it. About 1 in every 2 capsules is punctured and works correctly.
