What this unit is for
A price-attack brand: large capacity and output figures at the lowest end of the market, aimed squarely at first-time buyers shopping on price.
Best suited to: Buyers who need maximum capacity for the least money and accept the trade-offs. Less suited to: Buyers who value support, app quality or long-term resale.
Fridge for a day, camping for a weekend.
