Bests & Worsts Reviews from Amazon

I tinkered with this before I unveiled it to my kids. Its got a lot of capabilities. The simulator is very helpful deciding how to adjust your drawing. Connecting is not difficult, sometimes you have to refresh but its really simple and reliable once you are connected. The kids like to make the pre-coded shapes or just let him run for fun. Not a lot of direction. I would say the age should be at least 10+ not 7. Kids can make it work. If you don;t watch them they will drive it right off the paper and all over the table/floor. I work at a software company and some of our products are written in Java scripting. I haven't gone deep into the coding part but from what I saw is it is legitimate coding. My kids are not ready for that (oldest is 9). My hang ups is its kinda cumbersome to switch the markers and the instructions say if you have problems replace the batteries. That is true but you must have very new STRONG batteries. I hope rechargeable work. **Update** Rechargeable batteries do help and holding or taping the corners of the paper help keep the lines straight.
