I had low expectations after I watched this youtube video.
When it arrived it had a bent hopper, but more seriously it couldn't work due to a "tooth" on the crush disk left over from poor casting (couldn't turn the handle a full cycle) and a lack of spacer washers (grinding surfaces forced together stopping any rotation). Did I mention poor casting? Worst I've seen!
I rejected a £5 refund and suggestion I take it to a local store to fix (effing cheek!). I got a full refund and could keep the faulty mill, these are 3.7Kg and would have cost the seller a lot for return postage.
I reckoned I could spend 30 minutes sorting it out - much longer, I might as well just buy another one:
- filed down the tooth
- hammered the hopper into shape
- supplied three stainless washers each side to space the bar holding the grinding plate further from the mill
In the youtube video, the guy had to replace the two bolts that secure the shaft plate as they got stripped - with hand-tight butterfly nuts.
I've just crushed 500g of rye and I'm pleased with the results. I could easily do 5Kg before each brew if I switched to uncrushed sacks as well.
Conclusion: worth £15 delivered if it works, worth £0 delivered if you get a heap of poo you have to sort out yourself.
Corona mills have "Corona" cast on them, the cheap copies have "500" cast ion them instead. Seach ebay for "corn grain mill".
