  1. Could you please test residential door locks? Also, “commercial grade” spray bottles: how far they spray on narrowest, how wide they spray at widest, PSI they generate, viscosity of liquid they’ll spray, durability of handle, spray mechanism and the joint between that and bottle (we go through several each year because the joint-fitting cracks) and how well they resist things like chlorine bleach.
