i got this after my old battery started conking out halfway through cleaning, and wow what a difference, my vacuum runs like it's got a new lease on life, no more stopping to recharge every ten minutes, it handles my whole downstairs without a hitch, even with pets and kids making messes, installation was straightforward just popped it in and it worked right away, feels solid and reliable, no issues after a couple weeks of use, definitely recommend if you're tired of weak batteries
- Pros: this battery is a lifesaver for my vacuum, it lasts way longer than the original and powers through big cleaning sessions without dying, super easy to swap in and works with a few different brands i have around the house, no more mid-clean interruptions which is a huge win
- Cons: it was a bit pricey upfront compared to some no-name options, but seems worth it so far, had to double-check compatibility before buying to make sure it fit my specific model
