I'm pretty impressed with this learning tool. It seems to be sturdy enough for the occasional dropping from little hands. The cards are made of paper but are pretty thick and hopefully will stand up to whatever abuse is thrown their way. They are easy to insert so children shouldn't have a problem with them. It comes with a USB charger which is the USB C format. One nice thing about it is, that if the child loses interest, it will try to get their attention several times but if they don't respond it will automatically turn itself off to save the batteries. There are a really lot of cards and they are double sided with a total of 224 words and six songs. I mistakenly said in the video that I have included, that there are three songs but the listing says there are 6 and though I haven't verified that I imagine that is true. You should get hours and hours of learning from this. Overall I think this is a well designed product and you should give it a try. To help understand how I rate items: My philosophy is, that for a rating system to be effective, the highest rating and the lowest rating should be reserved for a relatively small percentage of the best and the worst products. If I give a product four stars, it is because I believe it is a very good product. To get five stars from me requires a product to go above and beyond and really impress me beyond my expectations. By the same token, a product has to be VERY, VERY bad to get only one star from me. One thing that I DON'T take into consideration with my ratings is price. I may make a general statement such as “this is a good value” but it will not affect my star rating. The reason is that product prices change, even from day-to-day. Also what one person may consider a good price someone else might not. I feel it is more important to review the quality and features of a product and let the buyer decide whether the current price is worth it to them. Another thing that I don't take into consideration are issues with shipping. This is because the seller does not always have control over that. Following is each of the five categories of *stars* and how I assign them to a product: ***** Five stars - The product exceeded my expectations. I really love it and would actively suggest it to friends and would certainly purchase it again if needed. **** Four stars - The product met my expectations. It does what it claims to do. I like it and would recommend it to someone if they asked about it. I would Most likely purchase it again if needed . *** Three stars - The product is average and for the most part does what it claims. There may be a few things I don't like about it. If I recommended it to someone, I would state my reservations. I may purchase it again if I could not find a better alternative. ** Two stars - The product fell far short of my expectations. It may, in some respects, do what it claims to do but has far too many problems to overlook. I would never recommended it to someone nor would I ever purchase it again. There is a good possibility I would return it. * One star - The product is terrible. It has way too many cons and few if any pros. I would actively warn my friends away from it and would most likely return it if possible.
