Review on Upgrade Your Dyson V7 Performance With Biswaye 21.6V V7 Battery Replacement - Compatible With Multiple Models by Jerry Bergstad
Too expensive. good for me
The overall product is is good. However, the batteries gave a shirt life on purpose. You buy the vacuum at a reasonable price and you are hooked into buying overpriced batteries with short life span.Old school marketing gimmick.
Pros
- All most twice as long of run time with this battery
Cons
- It may require a specialist to install the battery which may cost even more money
