Poor quality... seems to be a known issue with this particular set
Bond car was faulty from the beginning. Wouldn't sit flat. Adjusted but kept falling out of alignment. When on track and bushes adjusted, they both ran ok for about 30mins. Then Bond car died completely.
Maclaren kept on running but within 2hrs the mirrors both came off and this was only through what I would consider normal usage.
All in all very disappointed, non more so than my Son who was without a main present for most of Christmas day.
