I hand pick companies that make products I have already tested to become sponsors. These products are of good quality in my opinion and the companies offer good customer support. They don't have to be large but most have been. Note that Easy Motion is no longer an advertiser but their new models still score high based on the quality of design, availability and price point. I continue to reject proposals from companies who expressed interest in advertising but do not offer products I feel comfortable promoting. Most of my scoring is inflated but it also varies year to year as new models come out... so a 10/10 in 2013 is much different than a 10/10 in 2015. I also provide the full writeup and pros/cons to help clarify and extend the rating... There are no reviews without at least a couple of cons and some have many despite receiving a higher rating. Also, some of the older reviews have less insightful or irrelevant cons given the product in question, this is just me getting better over time and trading new reviews vs. reworking older ones. I hope this helps clarify, thanks for your support
