Hot Wheels Track Set and 1 Hot Wheels Car, Infinity Loop Track Kit

my grandson loves playing with it

Bought this for a Christmas gift and it barely works. The pieces holding the loops up protrude through the track and knocks cars off it. The tracks are twisted too much and doesn't line up well at connections. If Mattel was smart enough to use their own track alignment pieces for connections, the track might work better. The mechanical starter is also incredibly difficult to use. Hit to hard and the car flies off immediately after the track changes any direction, hit too soft and it can't make it up the first loop without falling off. Cars with the front lower spoiler will not work on this track at all. To get this track to work, the loops have to be at a specific angle the green corner piece bypassed, even with the correct car type it's about a 15% success rate with a 32 year old manchild operating it. 2 weeks after setting it up and the track sides have permanently deformed from the excessive bending angles. This is the first review on Mattel's website, don't believe any positive reviews after this, they are fake or paid for to counter this negative review because this track is garbage.
