Kobo Clara vs Kobo Glo

Kobo Clara and Kobo Glo are both small e-Ink readers with a 6-inch screen. Both are positioned as affordable mid-range devices, supporting a built-in screen backlight (so you can read even in low light). They offer touchscreen without physical buttons for scrolling, allow to download your own books in various formats (or purchase them from Kobo store), support a wide range of fonts, allow to adjust font size, margins and other reading parameters.

However, Kobo Glo is essentially the Clara's predecessor (and is no longer in production). It was released back in 2012 and was one of the first e-readers with a backlight on the market along with Kindle Paperwhite. It has less storage capacity, isn't waterproof and a bit larger and heavier (180g, 157 × 115 × 9.2 mm). The interface is less functional but is quite sufficient for smiple reading. Now you can get Kobo Glo for more affordable price than Clara.

Kobo Clara was released in 2018 and got improved backlighting with ComfortLight PRO technology, which allows to adjust color temperature (reduce blue light, which is especially important for healthy reading before sleep). It offers up to 8GB of memory, more modern design and improved body materials compared to the Glo. Later versions received a color screen, but it's not as comfortable to read.
