I think these cards are great for my 4.5yo. She understands patterns so it's great for her to know those answers, and the sequence sides give her something new to work on. I am intending to buy her another set of cards for her birthday. It's not something she uses every day, but she does enjoy them. They are portable (she even fits the pen in the box). It's great to have a different medium for learning other than computers, shows, and worksheets.
the first one i received did not come with a spicick or cork for the top. i contacted overstock, no problem. they were very nice on the phone and arranged to ship me a new one. they sent a shipping label to my printer and i sent the old one back[ at no cost to me]. a few days later i got the new one with all its parts in tact. i'm very happy; thank you so much.
