Amps is also a big difference in them as well, the higher the amps the longer it will run. The 40V are only like 5 amp. The Milwaukee are 18V but are 12.0 Amp for like weedeater and chainsaw, you do the math...

I'm waiting on the fall sales to complete my Ryobi set with a pole saw and weed eater.

Just wanted to give you a review. It's so nice just to pick up a cordless anything for a little growth or a few leaves. A primer bulb would now sound like too much trouble. I was a little anxious about going from an .095 trimmer line to the .085 but it gets things done. I have a lot of trimming to do and have yet to add new line. Love everything about it.

My son has an EGO cordless mower and string trimmer. Less than a year old and he just got the trimmer out of the shop and now the mower has bit the dust. Glad they are still under warranty but they are saying 5 to 6 weeks to fix the mower.

I am almost completely electric at home, and 50% at our place in central Texas. 14" chain saw, weedeater, leaf blower(s), drill, impact, skill saw, sawzall, and screwdriver - all Ryobi. One benefit with all of these tools, I have a large collection of batteries of various sizes, and can usually get smaller jobs completed pretty easily. My biggest concern was the small chainsaw, but happy to report I can accomplish quite a bit of cutting using just a few batteries - just not suited for felling big trees.

I still have echo weedeater for bigger jobs on our property, as well as a selection of gas chain saws, but I just got sick of trying to start my yard equipment after it sits, and rebuilding carbs. Even using non-eth gas, I still have problems.

I haven't needed a new lawnmower - yet, but think my next one at home will be electric.
