At $2 each I think it's excellent value. Last time I bought a DS18B20 out of 10 I only received bare chips and paid about $1.50 each. So the inclusion of the assembly in a complete waterproof package is outstanding value to me. Of course I find cheaper assembled units shipped from China, but there is real value in not having to wait long for delivery. The blocks came without documentation so there was no color code, but it's almost obvious. .red= VDDBlack= groundYellow= DQ
