EGO 56V Line Trimmer
My first pleasant surprise was at the register when the young lady decided to give me an unsolicited discount taking the price down from $399 to $360.

Unpacking it and putting it together was straight forward and painless and the battery charged up ready for its first use in the time it took me to assemble everything - approximately 20 minutes.
Out in the backyard it absolutely chewed through everything without batting an eyelid on a single charge of the 2.5 Ah battery pack - 3 foot high weeds, long grass it took it all in its stride. Colour me impressed.
Reading through the battery pack operator's manual a particular section caught my eye. Apparently the battery pack will automatically perform a self-maintenance function if left stored for one month and will self-discharge to 30% capacity before then entering a "sleep" mode. Interesting stuff.
