Very unreliable my friend used there service. arrived 1.5 hours late. so ended up paying an extortionate rate for very little time. alot of the "experiments" did not ammuse the children atall. i Myself used this company unbeknown my friend had (i only found out when we met up for coffee and it came up in conversation). again arrived 30 mins late for my child. Then rushed through everything he did. dropping liquid objects on 2 different occasions. also very rude answers to the children as if he just did not want to know. STEER CLEAR AT ALL COST!! read full review »
