Don't expect any customer support
Ordered a Ender 3 S1 Pro printer from their UK store, it arrived but the extruder was faulty so I have been dealing with their customer support to get a replacement. Note there is no customer support in the UK or office in the UK to contact. Communication via e-mail was.... difficult but eventually they agreed to send a replacement. I have been waiting for close to a month for the replacement, it still hasn't arrived. I am trying to get them to find out what's going on but communication again is.... well.. not responsive etc. By now I just want to return the printer and get my money back but this seems like you have to ship it back to China (?). There does not seem to be a return address in the UK. The printer has been sitting in a box for more than a month. I am fed up. Do not buy from them unless you want to take the gamble.
