Score: 88/100
Arrow ET501C
Score: 88/100Rankings

The Milwaukee 2447-20 is a compact, cordless 12V stapler designed for professionals needing portability and reduced hand fatigue. It excels in tight spaces with its lightweight design and impressive 1500-staple runtime. However, it is limited to T50 staples and requires purchasing batteries separately.

The Arrow ET501C is a cordless 5-in-1 professional staple and nail gun powered by a rechargeable lithium-ion battery, designed for versatile use across multiple trades. Its main trade-off is the requirement for two-handed operation and the separate purchase of fasteners. It is ideal for DIY enthusiasts and light professionals requiring a portable, multi-tool solution.
