After reading the customer evaluations, I came to the conclusion that the most important aspect is that the product has an exceptional price and quality, and that the customers don't make a lot of fuss about the fact that they got it on a budget even though they are hunting for diamonds. Either that, or you need to reduce your spending and purchase twice as much. Alternately, you will need to ride in a vehicle driven by a standard Shumkov. Who has to ride and not complain each year that the spikes are missing, etc., and who has to do it? That sums it up nicely.
