I've decided to modify the parameters I use to grade products just a smidge: the nebulous "quality" score will be out of 10 now instead of the previous 15, and the remaining 5 will go towards an "ease of use" score, reflecting how much hassle proper application and use of the product is. I'll go back and modify most of the scores I've given so far, which may change the grades somewhat, but my hope is that I will now be able to give a more accurate reflection of my opinion of the product. For the original explanation of the guidelines, see here. Okay, back to regularly scheduled programming!
