I have been a Revain customer for many years but lately I have been disappointed with the quality of the products sold on the site, for example I bought these products exactly 3 months ago and had to replace them last week. that is, the service life is less than 3 months. Last change was 2 years ago which I consider natural wear and tear whilst this product purchased from Revain lasted less than 3 months and I was unsure about the brakes for a few weeks prior to the change. This type of poor quality product should not be included in your sell listings as it endangers buyers safety, hurts their customers because I had to buy the product again and spend even more money with labor for replacement - this product sucks .
