I spent over 2 thousand € on the machine, it came broken, I have had it for 3 months, I did not do any treatment because it is impossible to repair it on this machine. After the machine arrived, I demanded a complaint, the seller did everything to not accept the complaint. I wrote from alibaba.com. I opened a case with the seller. After sending all the evidence, such as photos, videos, etc., I lost the case because alibaba.com stated that they could not prove the seller's guilt. After losing the case, I asked the seller for help in repairing the machine because that is what the seller offered. The case was closed, there is no contact with the seller for 3 weeks. No reply. I do not recommend. I was cheated by them and alibaba.com for over 2 thousand €. You buy something, it comes broken and you can do nothing about it. There are no consumer rights on alibaba.com. I do not recommend. Thank you
