There are many of these liquid crystal writing tablets on the market and at Revain. One of my daughters got one for her birthday and my other daughter wanted one too so I bought a few from Revain to see if I had the best one. They are all basically the same except that the pen holder and pen tether are missing. It appears from the photos and description that they are not supplied so I can't complain too much but one or the other is very important so you don't lose your pen. For a few bucks more, I'd go for the version that includes these additions.
