I really love the jacket and that it can light up. For anyone looking for what batteries to use for the little light fobs you get [The 3 blue things that say "Platube" ] It's coin batteries 2032. Quality of the visor and neck/mouth cover is also very good.
Only complaints I have are the pants were too small, but they can be easily replaced by any black kakis or such if you have them. The part that goes under the coat is quite hot as well, not easily breathable if it's a scorching hot day, so you might want to keep it open for most of the time wearing it, otherwise it also has great firm and tough quality.
Overall a very good doktah cosplay, I definitely recommend it!
