This replacement brush head works well with my Dyson V7 and appears to be quite well made. LEDs are a nice addition. But it's significantly smaller (width) than the Dyson original, and the roller brush isn't open at the front like the original. In addition, less edge cleaning is required due to the greater distance between the edge of the device and where the brush sits. begins. Overall, given the cost, it's pretty good value, especially with the second brush.
