What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Black+Decker LST136 is a popular 2-in-1 that swings between trimming and edging via its telescoping pole and tilting head. It carries a 4.4-star average across more than 8,000 Amazon reviews, and high-trust r/lawncare and r/Tools members specifically like the quick conversion to an edger and report that a single charge handles a typical yard; one long-running owner says it has worked great for a 5,000-plus-square-foot lawn. Home Depot and Walmart verified-purchase reviewers echo easy assembly and decent runtime.

The honest counterweight comes from high-trust community voices too. An r/BuyItForLife thread bluntly states Black+Decker is 'generally a terrible buy' for consumer-grade tools, and others describe the self-feeding head as occasionally fickle. So the consensus is more 'good value for light residential duty' than 'buy it for life.'
The takeaway: a sensible 40V pick for homeowners who want one tool to trim and edge a small-to-medium yard, with realistic expectations about long-term durability and an auto-feed head that some find finicky.
