As a brush, it performs its functions at 100%, I bought 2 brushes, for myself and for my girlfriend, both are satisfied with the quality of cleaning The only problem is to buy a new Clean head (standard). The sale is full of both original and Chinese replicas, but for the X3 brush. For X5, I did not find it anywhere for sale. The difference between the X3 and X5 of the attachments is the presence of an NFS chip so that the usage counter is automatically reset. So far, you have to buy for X3 and reset it manually in the application. The nozzles themselves, if you take the original, do not differ in quality from the complete one.
