After saying I thought if was a good looking bit of kit I have looked again and would note:
Quality, like Harry said the welds do look bad.
Design, having the only place to drain it in the place it is makes its coned bottom pointless as its not in the centre and there not a second tap higher up. The thermometer is pointless if you want to use it with any cooling solution but it does have a thermowell. So really no better than a 50L brew pot with a tap and thermowell.
The seller, is based in China, uses a German VAT no has 3 feedback on Amazon but trades under a different name on ebay and has 93 good feedback 1 bad. Based on the delivery time scale I think its shipped from China. But its likely a legit seller.
I don't know how amazon return policy works if you wanted to return it due to quality if its from outside the UK so no idea on the risk
