How it will show itself in practice, it will be seen over time. Purchased for personal use, not for professional use. For professionals working at heights (ceilings, communications, etc.), it makes sense to purchase more expensive analogues with battery power and remote control. In order not to run to the tool for on / off and other reconfigurations. Different pros: Outwardly, it looks decent. High-quality, rubberized plastic housing. Does not slip in the hand. Has some cons: Price. Battery powered. Battery-powered counterparts are even more expensive.
