I don't use hot but got sick of flimsy reels just recently when my year old Claber imploded at the spindle and buckled - my own fault, I had fitted a 100 m of new reinforced pole hose without reeling it on under pressure, tightly wound once in use with water pumped through it, it expanded !
Treated myself to a Proloc from Varitech £140 inc vat and delivery through their Ebay store. Its the dogs whatnots ! came supplied with two threaded brass barbed hose tails one for 1/2" hose on the inlet and the other micobore ( 6 mm ) for the reel hose although with a bit of force and heat did manage to get the 5 mm Gardiner reinforced pole hose on it, easy to bolt down in a van mount too.
What I also like about this reel is it is quite narrow but deep sides, seems to help with reeling hose in and keeping it neat for the next time its reeled out plus there is a lever you can screw in to lock the spindle while in transit.
