Flex is best
I recently purchased the Flex Impact Drill, and it has quickly become a staple in my toolkit.Performance:The drill delivers exceptional power and torque, making it ideal for a variety of tasks, from light household fixes to heavy-duty construction projects. The impact mechanism ensures efficient drilling and driving, even into tougher materials like concrete and dense wood.Design:The ergonomic grip and lightweight build make it comfortable to use for extended periods without causing strain. The compact size also allows me to work in tight spaces with ease.Battery Life:The included [battery specification, if applicable] offers impressive runtime, so I rarely need to stop to recharge. The quick-charging feature is a huge plus when I'm on the go.Features:I particularly appreciate the variable speed settings, which provide excellent control depending on the task. The built-in LED light is a thoughtful addition, helping me work in dimly lit areas.Durability:The drill feels solid and well-built, giving me confidence that it can withstand frequent use and tough conditions.The Flex Impact Drill is a high-quality, versatile tool that I highly recommend for both DIY enthusiasts and professionals. While it might be slightly pricier than some alternatives, the performance and reliability are worth every penny.

King of impacts
This thing is a monster. It has eaten everything I've thrown at it. Very powerful and I love that it has modes to be able to use some finesse instead of full brute power all the time. Quick eject is great. It's small, lightweight and feels great in my hand.

⭐️⭐️⭐️⭐️⭐️ Best Impact Driver I’ve Used – Highly Recommend
Delivery was right on time and the package arrived in great shape. I’ve been using this FLEX impact driver for a couple of months now, and it’s hands-down the best one I’ve owned. I work in concrete fastenings daily, and this thing has outperformed my expectations. It has power, durability, and hasn’t let me down once. I’ve been really impressed with the FLEX brand overall and will definitely be picking up more of their tools in the future!

Great price!
Great. I have a flex drill, batteries died. Bought this to have 2 batteries and a hammer drill. It's louder than a standard drill because of the impact quality. But it makes driving screws easier without having to use as much push force. You are going to need an extension to set your screw bits in.

ITs a workhorse
The FLEX 24V Compact Impact Driver is a powerhouse disguised as a lightweight tool. Despite its smaller frame, it packs enough torque to handle most jobs without breaking a sweat. The brushless motor means smoother performance and longer life, and paired with the 24V battery system, you get hours of reliable runtime before swapping packs. The multiple modes — especially the self-tapping screw mode — make it versatile for everything from furniture builds to tougher construction tasks.Sure, it’s not meant to replace the monster full-sized impacts for driving lag bolts into hardwood all day, but that’s not its purpose. For daily use, especially in tighter spaces, it shines. If you’re already invested in FLEX’s 24V platform, this driver feels like a no-brainer upgrade — compact, efficient, and genuinely fun to use.

No Adjustable Torque Settings
The driver seems well made and powerful but two negative observations 1) It’s heavy 2) The torque is not adjustable
