Cash flow is the quiet constraint behind model comparison: the cheapest option is rarely the one that frees the most working capital.
Why model comparison matters on the Nex 4
Compare on battery, capacity, coil range and total cost of ownership, not headline price.
Freight consolidation changes the answer to model comparison at container scale, which is why small and large buyers reach different conclusions.
Consumable availability often matters more to the customer than device features.
