Those pads are LC (Lake Country); and yes they are good. Many members here use them; I purchased a similar kit but with only the pads (already had the PC) and they seemed to work great for me...still using them 11 months after purchase. :2thumbs:
I would also pick up one of their pad cleaner tools so you don't have to worry about your pad loading up with residue...just give it a good spray with the hose, brush off what you can and turn the pc on 3-4 and spin putting the cleaner against the pad every so often...works great and you dont have to buy so many pads if you clean when needed. After polishing you can wash your pads in the washer, Ive been cleaning mine that way for 4-5 months now and have never had a problem!
