The set's pros include its replaceable nozzles, its two batteries, its compact charger, its adaptability, and its small size. particularly practical for routine tasks like trimming, grinding, and screwing on, as you can simply flip the nozzle open and get to work. Distinct disadvantages: the set includes limited consumables (such as a jigsaw blade that can only be used on wood) Nozzle repositioning can be tricky at first, but after an initial run-in period of one to two hours, it's no big deal.
