The entire array of two stroke lawn tools are obsolete with electric batteries and electric motors that are more compact, higher torque, quiter, and far less polluting.
Soon, they will be cheaper. Unfortunately EV based tools slotted in the luxury upscale segment, abut vastly declining battery costs still haven't trickled down to the consumer.
High density lfp and sodium ion and solid state should change this.
The other crappy thing is that the tools use their differing shapes and molds to lock in you to a single line of tools., so you can reuse batteries across tools only of the same maker (which enables you to have a second set of freshly charged batteries when the primary drains, and you can charge the battery will hold you use the second set)
Emer really need formalized standards to force battery companies to use an interchangeable standard like disposable batteries, electric plugs, railroad rails, etc
...and while they're at it, please force the plastic tote business to use a standard lid
