Sigma Electric Round Junction Box worked out well
this junction box is high quality and has all the needed plugs which makes it very flexible. I found it easy to work with and very sturdy. with the right connectors it can easily be watertight. I'd buy this again when I need one.

Better than the junk at Home Depot!
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. ... show more

Good price, as advertised.
I bought this to replace the box from a square application. It is good quality and didn’t give me any issues. I would recommend this product for the money.

Ring Hard-Wired Camera Install
Work great for what I needed. Used to mount a hardwired ring camera on the house. Easy to mount and install as long as the surface is properly prepped.

Ok
All works well, but the screw hole size is bigger than standard.

Great quality
Item is great quality and was perfect for mounting a Ring floodlight cam in the back yard. 1/4 the cost of my local hardware store. Came with the plug blanks.
