Review: Good value - I have had my trimmer for many years now and it works great! Battery was not lasting as long as it used to so that is why I purchased another. The old one still works...so it is great to charge it while the other is being used. Nice not to have to use a gas or electric trimmer. Good value for price. I hope to continue using for many years to come.
Review: So satisfied, great product - I am so delighted with the new battery, actually I think this one keeps the charge lot better than the one that came with the blower. I love the blower, it is light, easy to use on the sidewalk and patios, don't have to drag out the big blower. Have bought one for one of my daughters and I'm thinking of buying another one for another daughter. I have had it for 3 years, first time I had to order a new charger. . I would recommend this to all my friends.

### ⭐⭐⭐⭐ Good, but the Lithium Ion version was so much better.
*by D***F on July 15, 2020*

The NiCad version of this battery pack does what it's supposed to do, but the lithium ion version was so much better. Now, it seems that the lithium ion version is no longer available. It gave full power right up to self-shutdown and lasted longer on a charge than the NiCad. In contrast, the NiCad starts at full speed but eventually slows down until it's unusable, and it's running time on a full charge is much shorter than the lithium ion version. Also, the NiCad takes much longer to recharge than the lithium ion.
