We needed multiple bulbs but only had a single electrical box in a vaulted ceiling, so we needed a fixture like this. We also needed it to be compatible with a sloped ceiling, but this wasn't mentioned in the specs. I took a chance and bought it, and it worked out beautifully.
Pretty easy install, and with clear LED bulbs it has real nice character. The mounting base can be angled as needed, which made this a success.
The only complaint is some of the bulbs sockets are not perfectly aligned, ...
