The cars are ok and they are quick to dispatch and take your money but... try getting replacement parts!
After 6 months and 24 e-mails I am still trying to get a replacement part (despite sending the exact part that I needed back to them by Recorded Delivery)
Their service and communications have been incompetent at best and on occasion I have been treated quite rudely!
Dont waste your money here. Go to a proper model shop rather than an internet trader for this type of kit.
