Hosetract reels?

Was looking at some new reels. Local guy is selling some strackable hosetract reels almost brand new. Anybody have any experience with them?

I bought a used Power Line trailer that was built in Feb 2017 and it came with hosetract reels. Im currently looking to replace the reels right now because they are completely rusted. The super swivels that came on the reels are still good though. The guy who had the trailer before me kept it outside so maybe thats why they reels are rusted. I would go with stainless or aluminum.
