Good fit and quality - careless packaging
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
OK - I'm happy with most of the kit. The dead corner brushes are crammed into small bag and bent out of shape. It looks like 2 of the 6 in the kit I received might be usable. Since I can get 3 of these for the cost of the OEM kit, I suppose I'm still ahead of the game, but it would be nice if a little more care was taken in the packaging.

Better than original.
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
The pads are better than originals. A little bit thicker. They fit very well for a good price.

I can use my remote again
Style: 1 to 1 IR Repeater
I added a center channel speaker, and it was partially blocking the remote sensor. This solution works like a charm and has an easy setup. One end points towards the existing IR, and the other end goes where you are going to point the remote to. The only suggestion is to include a USB connector with the product, so I don't need to find one.
