                        Works great, batteries last a long a time and are able to keep a charge after being stored for weeks without use.

                        I’ve been slowing switching all my battery powered tools over to dewalt. Home Depot offers the best deals on batteries and tool bundles helping me add to the collection. These batteries have worked flawlessly for me so I keep grab spares whenever I can. I grabbed this to go with a 4” dewalt saw
                        by
                        Been using the DEWALT 20V MAX XR POWERSTACK 1.7Ah Battery for a while now and it’s honestly one of the best compact batteries DEWALT has made. Super lightweight but still gives strong power on impacts and drills. Perfect for overhead work or carrying all day without the extra weight of bigger packs. Charges fast, feels durable, and the power delivery is noticeably better than the regular 2Ah batteries. Runtime is solid for a compact battery, especially on everyday jobs. Definitely worth it if you want more power in a smaller size.”
                        by
                        Love the DeWalt system and this battery is small, compact, and powerful! Great addition for smaller tools to not have to take one of your big batteries.
                        by
                        These are great! Lasts a long time with lots of power. Works on all my black and yelloes

                        Not able to control the power
                        This 20v driver has three power settings first power setting is useless Second power settings is for braking and stripping screws And I never found the need to use the third power setting.

                          DeWalt DCF850 - COMPLETE FAIL!
                          I've been buying DeWalt almost exclusively for decades; this is the first fail. I bought this for occasional use. When it works it's a real wrist-saver. But after driving a small number of screws on a few odd jobs over the past 8 months, it's dead. Sometimes it works for a second or 2 and then quits. The same battery lasts hours in my DCD771, which has performed flawlessly for years. I hope this is a one-off failure (they do happen) and not a sign of DeWalt quality. I'd be very hesitant to buy another DeWalt tool now though.

                              Great compact impact
                              Great compact 20v impact. Hoping dewalt can make more smaller tools that have low vibration in the future. I prefer the compact form factor even if it sacrifices power.

                                I bought one , used it for driving 10mm x 3/4” sheet metal screws , it worked fine for about 3 days , then had no power , I returned it , got another new one and same thing happened on day one , literally less than 1 hour use , I tried changing batteries , still junk , it worked like I’d expect one that was 3-4 years old
