China scammers.
Bought an ender-3 S1 Pro. Still working on that trying to get tramming right. Ordered sonic pad and serial cable. Over charged by £7.99. Sonic pad was a returned item to Amazon and parts missing, no cable. There is NO UK staff, all emails go to China, phone number is China, You are dealing with an unaccountable,uninterested, bunch of scammers.
