I have not used this box, but first impressions are quite good. The friction hinge is nice and there is a decent sized palette. Combined with its low weight, this pochade box is towards the top on my palette area to weight efficiency ratio.
One major flaw I see with the box though is the very limited gap between the palette and the lid. This means that the box looks unsuitable to me for painters who like to paint impasto, and who carry a day’s worth of paints with them inside the box rather than carrying tubes. This accounts for my rating. If you paint very thinly, then I would probably give it a higher rating.
Another problem is that it is not drilled to hold paint brushes, and that by the time you add two side trays, a cinch to hold it together and a magnetic side closure, you have got a lot of pieces to lose.
