These relays do exactly what they stand for. They are great value at their current price and for what they do. However, they come without instructions. I wrote to the seller who kindly sent instructions that helped a little. They let me unwrap them - but that's only because I deal with electronics all the time. The instructions were in horribly broken English. If a manufacturer and/or seller wants satisfied customers - and ones who keep coming back - they have to pay someone to write detailed instructions in their FIRST language, English.
