Purchased as a replacement to charge the battery for my Worx HedgeTrimmer. Works great! Charges fast, and the charge appears to last. Very easy to use, fits the battery perfectly. Seems like it will last me a great while. Perfect for what I needed it for and great value for the price. Highly recommend if you're also looking for a replacement to charge this type of battery.
