I have tried the kit on my 50-inch LG plasma.
Unfortunately, I did everything lubricated full now and strips on the display.
The plastic box is useless because the sponge is always crap because it absorbs anything and flies out of the holder.
The microfiber cloth is also very small and does not keep fest.Kratzer or similar makes it but can not.
Conclusion:
Rather spend a few more euros.
