At first it took a while for the compartments to reach their set temps. I'm not sure if it is because I had filled it with contents already but probably plays a role. Overall the product does not disappoint! They even included the upgraded 12V adapter for DC to DC, that's a $15 value for free! Set Power is awesome! Build quality, packaging, ease of purchase, and last but not least, the best dang deal out there for us normal folks! Been looking for one of these pups for a decade now and I'm so happy 😊 Thank you Set Power!
