Summary: Greenworks brand was founded in the USA in 2009 (but this tool is made in China). My go to power tool brand is Milwaukee, M12 and M18 Fuel, so I'll be making some comparison there. For Outdoor Power Equipment (OPE), my go to brand is Ego 56V. Also Vine reviewed the other Greenworks tools below. Adding three tools which I purchased to this review: Hammer Drill (tool ONLY), charger (dual-port), 13" string trimmer. Observations: Right off the bat, Greenworks is not quite as good as Milwaukee in my opinion. GW does have a 80V line, which is very competitive and comparable to the Ego 56V line. I have been a diehard Milwaukee fan, so I ordered this to evaluate the Greenworks 24V offering. Overall, I am impressed with the overall fit & finish. Both Milwaukee and Greenworks are head and shoulders over the Chinese lithium offerings, especially when it comes to raw power. Some of the higher power (amperage) draw tools offer both a 4.0AH and 2.0AH offering; if that is true, then I would spend the money for the larger battery as it costs less when bought in the combo sets (e.g. SDS drill, 1/2" impact, angle grinder, etc.). The heat gun is another that really requires the 4.0AH battery. Observations (NEW ADDS): 1) The hammer drill has an overall 3.8 star rating, so I'll be doing additional testing to test/check the hammer drill function. In initial testing, I can turn the clutch setting to the lower 1/3 settings, and hold and force the clutch to engage; so possible that the clutch is disengaging too soon. 2) The dual-port charger I bought specifically, and instead of the single port charger because of the higher charging power. If you charge a single 4.0AH, it is pretty quick (about an hour), and if you put two batteries on there, then the time will double (half the power). Overall, the slower you charge any battery, the better off (and safer) it generally is. Lithium also should be stored at 30-50% for best longevity. 3) Decided to add the 13" trimmer because I wanted a lighter trimmer than my 15" Ego 56V, and this 13" GW 24V fits the task nicely. Good for quick touch ups, and when going up/down steep hills. This trimmer does need the 4.0AH vs. the 2.0AH for serious trimming sessions. The variable trigger works well to preserve battery life, and control the amount being cut. Recommendations: These power tools really make economic sense when you can get multiple tools with the same battery. When I first got into power tools, I did months of research, and ended up going with Milwaukee. However, the Greenworks 24V line would be more than sufficient for the average homeowner's project needs, especially given the wide range of available tools. Pros: Extensive family of tools (individual pros/cons/conclusion below). Cons: Less popular than Milwaukee (individual pros/cons/conclusion below). Conclusion: Overall, I rate most of the 24V GW line at 5-stars (but there are a few exceptions listed below) Recommending it, especially if you're adding to an existing Greenworks 24 volt collection.
