This is my second screw gun. True, the first one was with a 1.5 A battery. In general, it worked for almost 3 years at a construction site before the first breakdown. Installation of a weak current. Worked daily for almost 3 years. Not so long ago, the button began to tune in, sometimes it did not work. Ultimately it burned down. I replaced it with Chinese, worked for a couple more weeks and started to stink. Either the brushes have already died or the Chinese button has killed the engine. I got used to it very much, so I ordered the same one. Worked on medium load. A little metal drilling, a few metal bugs. Basically, he twisted black self-tapping screws into drywall and Armstrong ceiling. Who needs a shurikov for drywall and other similar work. Take it, you won't regret it. Top for home. Batteries by the way from the first Shurik to this day work.
