Low quality tips, in the description indicate that they range from 200° to 450° but if a temperature higher than 290°-300° is set the station cannot set the chosen temperature which changes continuously, and shortly after the word "plug" appears if use the tips that I already have and that I have always purchased on Aliexpress this defect does not occur, it is clear that these tips are not working properly it is the first and last time that I purchase in this store
All is OK! Thanks!
