Model 132R. Works perfectly and hasn’t been used a bunch. I just moved to a place where it’s not practical to use an extension cord, so I’m on the “buying new batteries forever treadmill”. Yeehaw.
There was some confusion, so I am stating more emphatically - 120 V - as in it plugs into an extension cord.
Anyway, if you’ve got a small yard, this is perfect. Powerful, easy to reload, and compatible with lots of other attachments. Uses a pretty durable .080 trimmer line.
I bought it used for $50 a year ago and used it 2x. Price firm.
