Review on Upgrade Your Dyson V7 Performance With Biswaye 21.6V V7 Battery Replacement - Compatible With Multiple Models by Mike Sevenfourgd
So far so good for my opinion
I bought one a year ago and it only lasted three months. The new one is going strong after three months. So far so good. It may reduce the lifespan of the vacuum.
Pros
- Easy to install and works as advertised. Much longer lasting per charge than stock battery.
Cons
- It may reduce the lifespan of the vacuum
