                  Awesome Light Stick
                  Bought this about a month ago. It has been very convenient and useful for my use case. It’s very durable and bright. Especially enjoying the versatility, rotation and mounting capabilities.

                    Great that is uses the same 4v rechargeable batteries! Wish Milwaukee would make a multi charger for them because you have to charge individually with usb chords.

                    An excellent flashlight that truly stands out. I've tried multiple brands over the years, and this is by far the best one I've owned. The light's color temperature is perfect for inspecting objects from a distance, making details easy to spot. What's most impressive is its durability. It has survived multiple drops in an industrial setting, including a free fall from over 20 feet—I'm still not sure how it's still working perfectly! This is a solid, reliable, and incredibly tough light that I highly recommend. Not only has it fallen on dry stuff but in puddles of water and is still surviving. The focal adjustment is great on this light Though the battery life is coming to its end after clocking in so many hours.

                        Not worth my money
                        This was my favorite flashlight used many dark nights and inside drop celings and underground running conduit and electrical wire as a commercial electrician for 20 years. This lights performance was sub-par when it came to length of battery life from day one although it was over par for performance of bulb brightness and size. I've only had a year and half to at most two years and it's stopped all together charging and bulb burning. Very disappointing as I had high expections for the cost vs sturdy and performance life out of a very expensive flashlight

                          The flashlight is good it’s a little bulky battery. Life is pretty excellent. I love the natural daylight feature, which gives you a diverse light spread and just lights up your work area.

                          Worst flashlight Milwaukee makes
                          Extremely disappointed – complete waste of money I bought this flashlight less than a year ago, and it’s already completely dead. I’ve only used it in my garage while working on cars — no drops, no rough use, nothing extreme. For the price and the Milwaukee name, I expected way better. This is hands down the worst Milwaukee product I’ve ever bought. Total letdown.
