This is a Yes!
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
I needed to change out my Dreame vacuum accessories but didn’t want to pay the huge amount for the name brand kit, this works beautifully and fit perfectly. I cannot tell a difference and it lasts just as long as the original!

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.
