However, the kit is equivalent to a collection of instruments that would cost between 20,000 and 30,000 dollars. Jigsaw: very ugly, no pendulum mechanism. But I invested in some quality blades, and now I make use of a reciprocating saw. Two batteries that have been completely charged. After using a jigsaw to make 11–12 cross cuts in a 50 x 100 beam, the first person sat down. No complaints. When the tool was set to screwdriver mode, the second battery survived for an additional day and a half at the construction site. It is also wonderful. A screwdriver that does not have a speed control. I exerted a little bit more pressure, and it instantly started turning like crazy and scraping the slots. To get a gentle twist, you should only lightly pull the trigger. And this makes things more difficult.
