COMMENTS AND FEEDBACK. Jessica: “Having ADHD and processing issues means that I read very slow because my brain can’t focus on the words enough to both read them and process what they mean at a decent pace. Using Bionic Reading® has allowed me to feel functional and productive when I’m reading something lengthy – it’s such a GAME CHANGER!” Lisa: “I have not read fiction for 20 years. I read what I have to read. It almost hurts my brain to read regular type. But now I will be reading fiction again! Bionic Reading® works for me and I can read 2–3 times faster! AMAZING! This is a LIFE CHANGER! Thank You!” Patrick: “OK, Bionic Reading® is the real deal. I already read quickly and this doubled it.” Reaction from Daniel: “Holy smokes you’re not kidding!” Carla: “WOW! I could read quickly and fluently using Bionic Reading®. Doing this helped me understand the context of the paragraph much better than when I have to squint and focus on each word, which tires me out and I lose focus. Bionic Reading® is brilliant!” Nestor: “Your tool is gorgeous, It’s helping me a lot. My sight is reduced because one of my transplanted corneas has become opaque and Bionic Reading® is helping me a lot to read easier and comprehend faster.” TYPOGRAPHY. DESIGN. SWITZERLAND.
