I have had this particular product for three months and I can't say it's a powerful tool. But... From the second day, the screw on the rotation switch that adjusts the drill's hammer function was coming loose, causing the switch to come off. This happened several times, three or four, until eventually the rotary switch broke and it doesn't work anymore, neither the hammer function nor the rotation. I do not recommend it, it is cheap and not durable! In other words, it is not suitable for professional use!

Very powerful. I use it for electrical installations with large drills and hole saws for switches. It requires a little caution when drilling into bricks because it is very powerful, while drilling into concrete is like butter. Its anti-vibration features make it the most comfortable tool I have ever used. Purely professional tool
