Cons:
- Battery fits not exact and can be plugged difficult.
- Battery can not be removed after the first insertion without damaging the device !!! That's a No!
- Color does not fit visually with the device. The DC 16 comes in orange-silver gray - this battery is black - how much charge may cost another plastic paint ???
Conclusion: would choose to look at all the reviews on identical batteries again next time for the original and I say this emphatically to be paid for by the company without Dyson !!!
