I consider such an insurance nowadays simply necessary, because you always run the risk in the acquisition of low-priced products to have to say goodbye to selfsame after the warranty period, as repairs are too expensive! - In my opinion, the problem lies in getting better prices to even lower production costs, which then in case of damage to discard the products leads, since repairs by nature can not be cheap! In addition, I believe that the producers also create it, not to be old to have their products, since they earn nothing else! It does not matter whether it products or expensive brand-name products is about "No name".
Therefore, such is an insurance a good investment!
