Lowest price seen for the product in the stores we read, on the day it was read, before sales tax. The model is the brand plus the name of the smart lock; the versions go in the table. The price range, the median and the position use only models with a score; the price comparison looks at models whose score is within 0.5 points.
The spec score doesn’t measure security or real battery life or durability, and the strong or weak point reading is just a comparison of numbers, not a buying recommendation.
