"We needed 2 folding posts to deter unwelcome visitors to our site. Unfortunately when folded down we have had several vehicles drive over them. The base plate has pushed downwards, making the posts hard to lock with our heavy duty padlocks. Please do not use these posts in traffic areas, it was a shame this was not explained in the product details. I am not sure if these vehicles have punctured their tyres as another reviewer has commented, but this is less an inconvenience to us than the damage to the post itself."
"This product is ideal if you have a contract with a tyre supplier, this is now the second tyre that it has burst on my car.. On the plus side if someone gets past it and steals your car they won't get far unless they carry spare tyres."
