This one ended up needing to be modded. The first night I tried to use it, the best I could get out of it was tepid water. I called downstairs and they told me there had been a boiler outage that had now been resolved. The next night, it was still busted so I called the front desk again, and they sent a maintenance guy in. He had to tighten the screw in the middle of the handle, and that took care of everything. All in all, a pretty decent shower handle once it was optimized.
