I have one very similar that I bought a million years ago.
In those days the reel was cast metal and they had a real stout gearbox.
Now days the reel is plastic and so are the gears.
I have no idea how they hold up.
On the positive side, you would be amased how many western supers you can shove through one of these in a day if you are on the ball and organized.
Nope! I'm not even going to post my record production with my old 9 frame and Maxant flail uncapper. No one would believe me and I'd probably get banned for telling tall tales.
Sufice it to say: If the gears, reel and the rest hold up, you will not need to upgrade for quite a few hives.
You will need to bolt it to the floor.
I have exactly ONE hive more than you.
That makes my opinion beyond question.
