Practical picks. Math included.
For every problem we pick one thing to buy, show what it costs to own for three years, and tell you who should skip it. We rank by score, even when the winner is something we earn nothing on.

How we score
- Every product type gets five public criteria with fixed weights. Two products of different types never share a score table.
- Every pick gets a 3-year cost of ownership: the price, the parts you keep buying, and the power it uses.
- Articles say plainly whether we tested the product in person or researched it. Read the method ›
