I've got 2 each of 2 different hose reels.

I bought 2 from Rural King for 1 location that were often on sale for $49.99.

They were a blue version of the Tektons below.

I see they are no longer listed and instead Rural King shows these as their low price model.

And 2 higher priced models.

Also bought 2 of the red Tekton ones from TSC for another location. Those were $69.99 on sale I believe when I bought them but are a lot higher now.

Look exactly the same as the high dollar Cox reels have had no issues with any of them so far. The hose may not be as high quality but so far no complaints with the actual reel or mechanism. Probably all roll down the same line and get painted various colors and get different name stickers on them. Other than paint color they appear to be the exact same construction.

Something even cheaper without spring recoil.

I see no reason to overpay for name brand reels, some of these get quite expensive for basically the same design.
