"I got this box a few days ago and I'm amazed what you are able to build with those blocks. This is the first box that I build test, take apart and build something totally different al the time. And the fun doesn't stop there, because when your done building you can start write a program and download it to your robot using bluetooth and test it. Some may think this box is too expensive, but I can say if you compare this to other robots and the option you have with those robots this package is the best value out there.
Pro's: - The bluetooth connection to connect the NXT2.0 block to your PC, mobile phone and even other NXT2.0 blocks - You are able to upgrade your set with extra sensors from hitechnics to build even better robots. - If you prefer to program by typing instead of the easy drag and drop system in the included software then there are also lot's of options to - If you are out of ideas what to build next then there are lot's of video's on the internet or even great books to help you in the right direction.
Con's: - All parts in the box where only in bags and to make sure you don't lose any pieces you need to buy something to sort the blocks in. I liked the older Technics boxes wich had a plastic tray inside the original box to keep the extra parts in. - It's not always easy to replace the batteries in some models, but that is to be expected, so the batterypack is the next lego item on my wishlist. - The display would be better with a backlight, because in darker surroundings it is hard to read."
