I purchased this product one year ago. Since that time it has 1. Refused to take a charge, 2. The cheap plastic "switch lever" broke, and 3. Today it refused to do less than half the lawn it would when new. This means one more trip into Seattle to have the batteries replaced [I hope] under warranty. It is also much heavier than the "corded" model due to the weight of the batteries.
