I have a few of the HF black steel reels - couple 25's, rest 50's. No probs with the reels, can't say the same for their hoses. One of the 50's the hose was so checked after being in service for a couple MONTHS, I changed it out for one of their "diablo" black hoses - so far I'm not sure if that one's gonna be any better, time will tell.
No leaks directly attributed to the reels and their connections, but I'm addicted to QD's (my various shop spaces are still kinda "fluid") - My Dev-Air 5 horse 80 gallon comp is pressure lubed and rated to run 24/7/365, so when I get up I open the main tank valve and I shut it when I quit for the day.
"Mrs. Bukit" is as addicted to having compressed air (after living with ME for 55 years

) that we now BOTH agree that if EITHER of us dies the same time the compressor does, it's the compressor that'll get replaced FIRST (or ONLY

) ...Steve
