I will not be responsible for personal injuries, injuries to others or any living being, or any damage to your car, or any property damage.

Monetary disclaimer: I do not make commission, or profits or any kind of monetary gain from the sale of the Protool coding software by bimmergeeks.

Sponsorship disclaimer: The way my reviews work is that I determine what product that I want to buy and actually use on my own car, and during this process the product that I end up choosing is what I believe is the best option on the market. I then reach out to the company offering the product and ask them if they would be willing to sponsor me in a review, if the answer is yes then I write a review, if the answer is no I would end up buying the product (sometimes at a later date) but I wouldn’t complete a detailed review about it (I might write something, but not to the same extent as my standard reviews). But the critical thing is that I reach out for a sponsorship and not the other way around, this means that the products I am reviewing are actually things I believe in and would use on my own car. This also means that I am not being paid to review something I do not care about. Would I do a review if a sponsor reached out to me? The answer would depend on if I believed in the product, and I would make it clear in my review if this were the case. But at the time of writing this review, such an interaction has not occurred yet.

Time of writing disclaimer: everything I am writing about in this review is described at the time of writing and may not be updated in the future, so there is a potential that things are no longer accurate in my comparisons as parts are changed and upgraded as time passes.

Bias and comparison disclaimer: Throughout this review I will attempt to be as unbiased as possible while drawing comparisons to other products.

Mistakes and Inaccuracies Disclaimer: Throughout my review I will try to be as factually accurate as possible, but there are always chances that I make mistakes and write things that are incorrect/false. If this is the case please point it out to me and if indeed it is true that I am incorrect, I will correct these mistakes and apologize for them. Afterall I am only human, so mistakes can and will inevitably happen.

Subjective Disclaimer: Please note, these reviews are also written in my own opinion, so when I am comparing different products to determine what I see as the best, there are many factors that I go through to form this opinion. Obviously there will be disagreements between people, so I will do my best to objectively determine what I deem to be the best, but at the end of the day it is still just my own opinion whether it be right or wrong. Take whatever I say in my reviews with a grain of salt.

Information Disclaimer: I read a lot of material over the years just out of sheer interest or to make these reviews. I also accumulated a lot of knowledge over my many years of education that are really relevant to cars (Physics, Chemistry, and Mathematics). That being said, my reviews are mostly based on this accumulated knowledge and I cannot always cite these sources due to the original source material possibly being lost to time, or there being so much knowledge compiled to make a single point. So, when possible I will cite my source(s) (for example data on tensile strength of a metal, or peer reviewed research). There are cases when I get information from blog posts, youtube videos, or forum posts I may not cite it, because I go through a lot of these sources only to use the gained knowledge in a small section of my review and it is not feasible to list them all. So pretty much what I am trying to say is I am not citing “common knowledge” – I will cite peer reviewed research and photos though (if applicable or used), or really explicit user experiences (if applicable or used).
