Satisfied with the product, I recommend it to everyone.
It is impossible to detach the handle from the pipe, the size does not match a little (fractions of millimeters). Vacuum cleaner model DC29. Overall, I recommend it, but with reservations.
Pros
The quality is similar to the original, compared with the old pen. Sits tight, but this is a drawback
Cons
It sits very tightly on the side of the pipe, it will not be possible to remove it. Once collected, you will not understand
