What can I say, great value for the money. I only needed 2 but now I have some spares for future projects. They got the job done, nothing more I can say.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
