Nice quality pcbs. Dtwonder is using para rex, a reliable and competent delivery services, much much faster than the usual unreliable mail americas.
And tech support is truly excellent. Fast and accurate.
I now own several of the 4, 8 and 16 relay boards to meet my needs.
My only recommendation would be to provide space on the pcb for the snubber rc components. Adding them to the screw terminal is tedious.
