Nice packaging, arrived early!
I love that these come in a plastic canister with lid, all tidy, for stowing in my shed. I have a bunch of 5-foot 1/2" EMT conduit that I plan to put together in double or triple lengths to top t-post trellises as I get new beds built. I know that eventually I will use dozens of these connectors, so I was glad to get a good price on them. And they came earlier than expected!

Good Buy
This was a cheap purchase and they are better looking than what you get at Home Depot or Lowes. I am making finales for curtain rods out of electrical conduit and this pack (I got 2 packs) was so inexpensive!

Inside of coupler not deburred and does not slide onto conduit.
The inside of the couplers had a large burr where the screw goes in. This prevented the coupler from sliding all the way onto the conduit. I had to take a small grinder to remove the burr from the inside of the coupler which wasted a lot time. Will not buy this brand again.
