I'm in robot mode gears and wind charger they look good as robot mode in vehicle mode I suggest you go to a video the instructions are not that good that good when you follow the video the only one I noticed that everyone had a problem with is gears and I have the same problem the gear vehicle does not connect it's a hard time to connect into vehicle mode that's the only problem I have with gears is it worth a buy if you going to keep on robot mode yes vehicle mode give the one that's going to be annoying he doesn't want to connect the stubs just keep flopping so that's the only problem I had. For me I'm going to keep him in robot mode but if your person I like transforming them I don't know they're by for some not everyone would like this transformation especially with the gears and not connecting with so it's up to you
