Title: It can use improvement
Review: I would give these chocks second thoughts if I had to use them on hard surfaces likeconcrete or asphalt . It seems it would slip on these surfaces since the chocks are entirely made of plastic .They are strong but it would have been better if the company incorporated rubber on the bottom toavoid slippage . They are OK for dirt and gravel surfaces .My primary use for them are for a light utility trailer . I would never use these chocks for cars or light trucks . Too risky !
