"Most of the new buttons are very good in terms of sound quality. One or two seem to be lesser, the sound is not clear, a bit muffled and not so loud as the others. They are definitely better than the older ones. Batteries last long. I love how compact they are! (Even though this makes writing or symbolizing commands a bit trickier) \r\nI'm in love with this system!"

"The surface of the hextiles has little dots on it. This has made it a bit more difficult to stick tape on them. The color is solid and not just the top.\r\nThey are very firm. I love how plain and simple they are."
