They have been in operation for the second year so far, but there is almost no wear; this has been the most satisfying choice for me so far in terms of pricing and the quality of the product. Below are some advantages: Predictably managed, with no rutting present. It works nicely with the speeds I drive at and the way I drive. The level of comfort and loudness is satisfactory. I would also like to mention that I was content with the price. The brand of the machine is Shniva; the price tag is far lower than typical; nonetheless, the quality is still adequate. Cons: There are questions that are only on certain off-road, and while I am unable to totally avoid it, it is to my advantage that there aren't a lot of them. The comfort level drops whenever the vehicle experiences a jump like that, regardless of how the vehicle was injured.
