ONYX BOOX MAX Lumi 2 is another 13.3” or A3 sized E Ink Tablet with a front light and dual touch controls. This model is a bit older then their latest A3 sized device i.e Onyx Boox Tab Ultra.

The body of Boox Lumi 2  is made of lightweight and durable aluminum-magnesium alloy and the screen is covered with Asahi protective glass. Making it durable and giving it a premium look.

Bottom Line

An all-rounder e-ink tablets, gives a lot of options for reading, writing, drawing, listening, and note-taking just like an android tablet. It isn’t as feature loaded as the Tab Ultra but in our opinion the price is justifiable with the features and quality of the product is considered.

The Onyx Boox Nova Air comes in two variants. Onyx Boox Nova Air and Onyx Boox Nova Air Color. Both of the devices have the same screen size but Onyx Boox Nova Air color features a 7.8 inch E INK Carta HD and E INK Kaleido Plus color filter array. The B&W display has 300 PPI and the color has 100 PPI. Though the technology of color E Ink Tablets is quite new but I think its still great for those who want to read Mangas 

The screen is flush with the bezel and protected by a AG glass flat cover-lens. The front light has 36 white and amber LED lights with color temperature system. The dual-tone front lights in refreshing white and cozy yellow make the 4,096 colors more comfortable to view in any environment.

Bottom Line

We think the colored variant is the best E ink tablet for this price. The size is A6 and if you are looking for a more portable device and are more into reading Manga then we think this will be the best option for you.
