To date, the best product of this type

I am in my third reading light, and frankly, for me, the Aura HD is by far the best and most comfortable.
The size and the display quality are an element of pure pleasure when playing, I would say superior in quality to a paperback book whose print quality is sometimes poor.
The interest and quality of the backlight, without reflection, make it an unparalleled tool for reading at night without disturbing anyone (liseur insomniac, here is the unstoppable object that will reconcile you with your partner ;-))
I am not an advocate of a particular brand, but when I see some reviews, given my experience of this material, I often find them ridiculous and a certain bias.
From my point of view, one criticism to be made is that of the price. Although the quality is to go, 170 is too expensive for a "simple" text display. That said, no one is forced to buy it, and I can not blame myself even though I bought it. Paradoxically, I do not regret one second.
Finally, if you're a regular reader, this device will be a must. However, given the price, if you are a casual reader, try a less onéreus model
