Q: I need to buy a new child seat, but the prices are high. There are lots of second-hand seats for sale on internet auction sites such as eBay, but I am concerned that buying a used one might not be a good idea. Can you advise?
A: You should never buy a second-hand child seat - either on the internet or anywhere else.
This is because it's impossible to tell simply by looking at it whether a child seat has been damaged.
If it has, the seat might not provide adequate protection to your child in the event of an accident.
Also, the seat might not come with a user manual. Without proper instructions on how to fit it to your vehicle, you could compromise its effectiveness by fitting it incorrectly.
