Ok - so.... LOVE LOVE LOVE this company and product range. This is my baby/young child gift of choice, hands down. I have been giving sets of these books to friends and relatives for a few years now, and the recipients (Both parents and children) are enthusiastic consumers. Many have gone on to expand their collection. I usually give gifts of the Spanish sets, but also a few Mandarin. I even keep a set in my Art studio for children when their parents come to visit... & they are used & appreciated all around. Frankly I find them fun to play with myself, and showed them to a Chinese woman who has moved here and is just learning to speak English. I grew up learning to be somewhat proficient in French, but enjoy playing with the Spanish books. Good Investment.....
