I purchased this miracle - the unit somewhere in the middle of 2022. I chose by impact force only from branded ones (implying convenience and reliability). Main works 67 with a crown undercuts and a drill 6 under a dupel - a clamp. Well, somewhere else with a spatula to clean up the little things . How much I work with them - I swear so much. To change (pull out the snap-in from the cartridge, sometimes it is necessary to hammer it with a drill or a crown, sometimes the anther from the cartridge (remove directly onto the snap-in shank), sometimes it just swears enough . new ones) but . the barrel is hardened to the campaign really to the conscience. Next . Switch modes to swotting to translate - it's just a godsend! Such a chic simulator to swing your fingers, there is nothing more to say about it. . And itโs a pity to throw away this device - itโs still working and expensive, and, after all, the reptile does not burn out, although it heats up very much during long-term work. I wonโt wish to buy such a perf for an enemy).
