in terms of the seller, no complaints it delivered on time. about the product, the designer was not the little son of Eiffel. there was a design error for mounting and if we do not take a hammer or straighten parts irons u, one remains before the product with a headache wondering if we do it right. nobody ever mounted this designer distributor. Briefly once tinkered certain parts, (u irons that are diagonally) the product is valid. I hope that the engineer will not be transferred to a nuclear power plant.
