Love this! Great for edging and lining up everything. Very great price. Easy to change out string and self feeding. Bought 2- 1 for each property!!!

After a year the auto feed just lets line out constantly. The small plastic retaining pin on the spool housing broke and that's the problem. Just cheap construction.

I got a B&D LST140 several years ago, and replaced the housing once and the gears twice. Worked for 4 years until the motor burned out. A new motor was almost as much as a new unit, so we got a new unit. Got too much invested in the batteries to start changing equipment lines. The new version of the 140 has a stationary handle which means you need to be a specific height to use it without tiring your off-arm. The vents on the top of the motor housing have melted, which indicates serious flaws in the redesign. But the major issue is that it can only be used for as many as ten minutes before the motor starts grinding as if it's overheating. It has to cool down for a half hour or more before it can be used without grinding. And then sporadically it will just not go at all, as if the motor is completely burned out. We've had this one for three months, and have used it four times. It's now sitting on the porch trying to cool off so I can finish the last 12 feet of the sidewalk.

This is a terrible trimmer compared to my old B&D.. I cant trim more than 30 ft without the cheap plastic handle slipping positions 3 or 4 times. I finally just left the handle in the top position that it finally stopped in and had forearm cramping within in 10 mins. Not a user friendly model at all. Also my old battery had no problem getting through my entire yard with plenty to spare. This new battery barely made it to the end of my yard. Hopefully I can return after 1 use but I have already thrown out the box so I guess Im stuck with this what I refer to as a "toy" weedeater plastic piece of junk.
