### ⭐⭐⭐⭐⭐ It works

It works good price

### ⭐⭐⭐⭐⭐ Better than the junk at Home Depot!
*by C***N on December 17, 2025*

The FEIT bulbs seem superior to those we have been buying at Home Depot, where there seems to be only one brand. The Home Depot bulbs have a range of issues: flickering, not screwing into the socket properly, burning out early. These FEIT bulbs are doing great so far. We have FEIT security cameras, so we trust the brand.
