Pros
Pro Perfect for light-duty jobs
This drill is suitable for working with soft materials, such as plastics, wood, and drywall. It is powerful enough to do light-duty drilling and screwdriving.
Pro Lightweight and compact
Being only 2.5" wide and weighing only about 2.14 pounds, it's perfectly suitable to be used single-handedly. The small form factor makes it perfect for working in tight and cramped spaces, where larger drills would simply not fit.
Pro Decent power efficiency
The 2.0 Amp-hour battery performs surprisingly well when the drill is used for its intended purposes (small-sized jobs). A field test conducted by Pro Tools Review online magazine has shown that a single charge is enough to drive 51 three-inch screws.
Pro Perfect for tight spaces
The small size makes it useful when you need to drill holes and drive screws in tight areas, where regular-sized drills just can't fit.
Pro The drill head can rotate
The drill’s standout feature is its articulated drill head, which can be set to five different angles ranging from 90 degrees to 180 degrees. Due to this flexibility, this cordless drill is perfect for doing work in hard-to-reach small spaces.
Pro Good for working with soft materials
This cordless drill has enough power to work with soft materials, like wood, plastics, plywood, and drywall. It's suitable for both drilling and screwdriving.
Pro Very portable
The Bosch PS11-2A is easy to carry around as it weighs only 2.2 pounds. The 3.5" wide handle makes this power tool perfect for people who like to work single-handedly.
Pro Fast charging speed
It takes only 30 minutes to charge this drill's 2.0 Ah battery. This is a decent time, considering that the other cordless drills require between 60 and 90 minutes long charging time for their batteries. A single charge of the 2.0 Ah battery will give you several minutes of working time.
Cons
Con Bad for heavy-duty use
As the small ⅜" chuck and 265 inch-pound torque suggest, this tool is suitable only for light applications. Anything that requires high speeds and huge torque, like concrete drilling, is out of the question.
Con Poor chuck design
The design of this tool’s chuck is far from being ideal. First of all, at the size of only ⅜", it's simply small. Additionally, the Bosch's keyless chucks are very well known for being loose. This drill is not an exception as the chuck does not have any self-tightening mechanism. Every time the drill stops, the chuck untightens a little.
Con Unsuitable for heavy-duty use
With only 101 inch-pounds of torque, this cordless tool is not suitable for heavy-duty applications, such as concrete or metal drilling. Large diameter wooden drilling might also cause troubles.
