This was an awesome purchase. I would never expect a gadget like this to replace the time you need to spend with a child to help them learn to read, but I just hoped it would add to my son’s curiosity about words and be an added fun way to expose him to reading. It has surpassed my expectations.My son is 5 and recently diagnosed with ADHD and likely has autism as well. He is very smart but impatient with reading most of the time. He is in SK at a French first language school so he has only learned French letter sounds and the beginnings of reading French in school. His only exposure to English letter sounds and reading English words has been at home.I have been going through these books with him, mostly letting him touch the words one by one with the pen to hear them, after first touching the symbol that reads both of the pages fluently. This way it ensures that he is looking at each word as he hears it being voiced. When he is in a more patient mood, I will ask him to read the page on his own after touching each word and hearing them. He is doing it mostly from memory that way, but it’s still good practise. I showed the pen’s functions to my mom too, who was a grade 2 teacher for many years and then a JK/SK teacher for many years (now retired). She was also impressed, although we both agreed that when the symbol is touched to read both pages at once, they are read much too quickly. It is too fast for me to be able to point to each word as they are read.I love that it also has the options to switch the function of the pen so that it sounds out the words with the sound of each letter (except for words like “the” which are highlighted and just voiced as “the”), or says the letter names of each letter. I think learning the sounds that letters make is more important than learning the letter names (or how to spell a word by saying the letter names), but it’s still nice to expose them to a variety of ways to look at words/spelling/reading.The pen also works if you point to various parts of the pictures in the books, making sound effects or saying things that each character might be saying in the picture. There are also other functions on the pen like songs and audiobooks which my son has flipped through but we haven’t explored yet. So far my son has been able to listen to me when I tell him he is allowed to point it at the pictures or explore the other functions only after we read the words of the book, so they haven’t been too much of a distraction and act as a bit of a reward or a break after reading each page.Overall I am very impressed and I have no doubt this (along with the many other approaches we’re taking) will help my son learn to read.

Easy to use and no small or easily list pieces. You can read an entire sentence, a single word, or individual letters and their sounds. Great for travel and learning how to read.
