Very nice drill with a lot of power for the use I make of it. POSITIVE: 1. Its impact is incredible and it drills through concrete blocks effortlessly. 2. The clutch it has to prevent screw stripping works very well and reliably. 3. The chuck works with good accuracy. 4. The speeds are fine, although I would like the second speed to be faster, but it still gets the job done. 5. The motor is quite powerful and doesn't heat up much even under heavy use. NEGATIVE: 1. Its battery is relatively small, so for more professional use, it would be worth considering purchasing a larger one or another one with the same capacity. 2. The chuck sometimes loosens when I'm driving screws and doesn't tighten easily and reliably. 3. The motor has shut off a couple of times under heavy use, but when I put it in reverse and then back to normal, it works fine again (probably a safety feature to prevent overheating). 3. The battery doesn't have an indicator to show how much power it has left, so you don't know if it's empty or full. Conclusion... I really like this machine and it works great for the tasks I need it for. And in case it lacks power, I have a corded impact driver to rely on. For its price, it's a complete package. Now, I don't know how long it will last, but for now, it seems great, especially if I change the chuck and replace it with an iron one (if I can). That would be perfect. UPDATE 13/2/2023: I tested it on a pile of things, even a 25mm wood drill bit, and it easily made clear holes in about 5cm hard wood, averaging 13.5 holes with the second speed and a cheap wood drill bit. In other words, it's not worth it. With a better one, it would definitely take less time. I pushed the drill to its limits and it did get quite hot due to the brushed motor, but it didn't stop working because of temperature in any task I used it for. I was impressed by how much power it had. It will definitely be tested harder in future projects. If you let it rest a bit because excessive heat or load is the only thing that can damage it, it will never break and it will definitely get the job done for you. Now, if you want to drive large screws, this beast is not for you. It can handle screws up to 5cm, drills easily through wood, iron, and walls, but for driving large screws, you need an impact driver, not a cordless drill
