Tins are good especially at such a great price. They came with foam tape to cover holes to protect wiring and had templates to cut holes in the ceiling. Only criticism is that they were not packaged very well for shipping. Several cans were quite badly dented when they arrived. We only needed 21 of the 24 ordered so we got by, but needed a little tweaking and flexing prior to installation. But for this price, you really can't beat the value!
