I gave my son 2 years ago, the starter set (AZ) 2nd birthday (price of the set 34.95 EUR). Something better I could not buy. He loves it still. Here the pen fell into the water after a few weeks time, so I immediately ordered replacement (price approx. 26 EUR). The first pin I have to turn on without him, let it dry on the heater for a few days and it worked perfectly again. So now we had 2 functioning pins. The second pin was, however, already after some time 'software failure' and not played that from what he should. The volume could be only regulate on the PC. The first pin has completely given up the ghost after 1.5 years, the buttons simply could no longer be operated. By his own amateur repair it working again adequate, but not perfect. Now my son loves his TING-books (I think we have approx. 10 pieces) but still very, therefore I wanted to buy a new pen. This price increase within 2 years is definitely outrageous !! From 26 EUR to 35 EUR to 42 EUR for the blue. Since one can only hope that no one will buy at this price. The quality has not what you would expect for this price.
