Noise level matters to me too, especially if I plan to keep it in a quiet room or office. A compact and quiet unit is usually more practical for my everyday use.
Maintenance and Long-Term Value
One reason I consider Li-ion models is the lower maintenance burden. I like the idea of fewer battery replacements over the life of the unit, which can save time and money. When I compare the upfront price to long-term value, I focus on durability, battery life, and overall reliability rather than just the initial cost.
