Especially because of my pre-Berich Marketers I tried this remedy. Unfortunately, I found the means but only mediocre. I have used over the many years with leather seat cars have a wide variety of products for leather seats. Anything between cheap from the hardware store, as well as expensive purchased at BMW, the care effect overall was barely different. I especially hoped always to regain a leather scent, as he was in each case at the beginning always. The alleged professional quality of Reimair not helped with this request anyway even. I do not know exactly what it smells after treatment, but in any case not of leather and it also does not smell right pleasant. As such, it is an advantage that the alleged leather scent does not last as threatened for weeks, but was no longer to notice already on the 2nd day of me and my co-drivers. Four stars I give because it's not worse than others, but it is no better.
