Aggregate ratings are strongly positive, with most ratings in the highest category, but the sample is limited and no written customer feedback is supplied. The ratings do not identify which features customers liked or establish how the box performs. Buyers should weigh them separately from the manufacturer's claims about capacity, sealing and modular compatibility.
