This dvd laser lens cleaner is excellent. It has a choice of several langauages. I first found the need to use it when my PC would start to play cd/dvd discs but then it would stop completely during play for no apparent reason. I thought that i'd better use the dvd lens cleaner that i had previously purchased. I put the dvd lens cleaner in the PCs disc tray, loaded it & you can select your language the begin the cleaning process. Once the process had finished i played a cd to the end and it never stopped once! I have never had any other problems since i cleaned the laser lens!
