Polistil 960406 Pilot System Electric Racing Track

I bought this race track for my son. Polistil was a top brand when I was a child and I expected a quality product. Unfortunately after building the track (not very easy to put together the pieces we discovered that one car was defective and one of the 2 remote controllers did not work. Big disappointment, I had to ask for a refund and will now look for another brand. I would definitely not recommend this item, which by the way is not a cheap option considering the quality of the product.
