Just got these installed today in our newly remodeled kitchen. Love the look. Industrial and a touch modern. Super easy to adjust the length to exactly what you need. 
One glass globe was broken (by installer) and I've posted elsewhere asking where to find a replacement.

The glass seed is gorgeous; the shade itself has small holes drilled for the holding screws - but it really could benefit to have a plastic grommet to minimize risk of breaking (not why ours broke).

We used three pendant lights over a 72" length island.
