Great quality, very good price
Wiring my entire shop and found these to be a good price. I don't think any of these are necessarily easy to install but they work very well, just as they should. I would definitely buy again.

Great value
Worked really well with 14/3 Romex. The price was way better than just a few 5 packs at Depot.

Hey this will work on construction boxes and other products that has a knockout hose in it but I wish I would have got the 1/2-in instead of the 3/8
