Got this a few months ago and thought I'd give a short review. Saw, charger, and battery is $600. Most important bit of information: The 4Ah battery it ships with is undersized for the saw! This doesn't allow the saw to run near it's actual potential and provides a disappointing user experience. When fully charged it cuts well with a high chain speed if you let it run and don't lean into it but as the voltage drops it starts cutting out more easily. It also doesn't last long, I've had it only do about 10 cuts in 16 inch hard maple, (chain was a bit dull to be fair but still). The charger is a fast charger so in theory it can charge up in about 15 minutes but the pack gets hot during use and if you put it on the charger it might run the fan for about 15 minutes before it even starts charging the pack. It really needs the optional 5Ah battery which has a $330 price tag if bought separately and there is no option to substitute it for the 4Ah when buying the package. It can also take an 8Ah battery for $450 which is probably the best choice for power and run time, plus it would add even more weight. For some reason they decided to include Bluetooth in the batteries, I guess so you can check the charge with your phone? Maybe they could leave that out and drop the price a few bucks instead?

The saw itself is solidly constructed, better than most electrics I've seen, but it's also fairly heavy even with the undersized 4Ah pack. I'm living with it as is for now, hoping that battery prices eventually come down, or I may try to build my own custom pack.
This guy has some really good comparison videos with the saw, this one he uses all 3 batteries, 8Ah performs the best of course:

It's stuck at 50% and won't charge, saw will run for a few seconds then stop. Working on a warranty replacement, it may have been defective from the beginning and under performing the whole time.
