DS loves it! He'd never used the computer until 2 weeks ago and he worked it all out within 30minutes. He's finished the first map in less than 2 weeks (I got the 2 week free trial) and now I've received another 4 week free trial so he's starting again. I LOVE that I can leave him at the computer on his own for an hour at a time (he's limited to an hour MAX per day) and he will go through it all without needing me, but alot of the time I do come and sit with him for a while and he really enjoys that 1 on 1 time together.
DS has an amazing memory, so this has been really good for him. He is also applying what he's learnt to other areas and he's recognising words and I would say that he can read a few smaller words already. Once this 4 week trial finishes I will be buying the subscription.

Highly recommend it! Can't wait to see what 12 months worth does for him before he goes to school.
