Review on Upgrade Your Dyson V7 Performance With Biswaye 21.6V V7 Battery Replacement - Compatible With Multiple Models by Anthony Wilson
Great product - my new review
Great battery life, indeed better than the original. Only downside is that when removing the dyson from it's charge cradle, it now often sticks and needs pulling free.
Pros
- After a few months it still works well.
Cons
- It may not be compatible with some charging cradles
