My first battery chainsaw was a Lowes Kolbalt 18". No clutch and no brake, took forever to coast down. Dangerous and it only lasted about 6 months before just quitting electrically. They quit making them at the time so I got the EGO for the same money on warranty. And the battery ones have a lot more starting torque that easily will kick the chain off. It seems to me the bars are awful flexy anymore? I down sized my 18" to 16" and that's bigger than what I really need.Spent the winter clearing snowmobile trails of blow down with Milwaukee E saws. Good for small stuff, limbing but don't be in a hurry.
Since the E saw has no clutch to slip like a gas saw they kick off the chain really easy if you're in a hurry, even with a sharp chain trying to cut up 6+ in. frozen stuff.
No where near the power of gas but as said handy for quick small stuff especially in cold weather.
More dangerous for homeowners / casual users though, they will cut through safety chaps as no clutch to slip like a gas saw has when chain gets caught in the chap's fibers. Learnt that in a chainsaw safety class.
The 18" EGO one does have a very easy to work, tool free chain tightening and removal. And seems to have somewhat of a drag or brake to slow the chain down when you let up on the switch. Variable speed of course.
