For small jobs and the ability to take it with you in a backpack. You can buy an adapter and use it as a screwdriver, it will be a little heavy, but for a small amount of work, so as not to carry an extra tool, it is suitable. Pros: The perforator is most importantly light and not large in size. Worked with a 6 and 8mm drill. For a 10mm drill, it’s already hard to go, but it’s hardly possible on a brick. I bought a battery with 6 hours not original, it was enough for about 30 holes in good concrete with a 6 drill. Has some cons: High price. Does not replace a large full-fledged rotary hammer There is no jackhammer mode.
