## Customer Reviews

### ⭐⭐⭐⭐⭐ Very handy for stepping power in pwm signals.
*by T***J on August 7, 2025*

I have one of this brand solid state relays running my pickups electric fan at 12v with 250 hz pwm. Works great for this purpose and you can even get heat sinks for them.It's been on the truck over a year now and ~ 9000 miles, mostly in the heat.

### ⭐ Two ordered - two failed.
*by J***L on May 16, 2025*

Bought 2 of these thinking that possibility of one being bad was not unrealistic. Both failed. Installed completely within specifications and neither worked. On connection both relays closed the switched circuit without having the relay energized. Due to the nature of the project I could not fire the system up until beyond the window of ability to return so I seem to have no recourse. Not happy about that. I wound up ordering a TE brand relay (just one) and it worked perfectly on install. The TE relay is also made in China, but clearly to higher standards.

### ⭐⭐⭐⭐⭐ Awesome piece of tech I wish I knew about a long time ago.
*by A***Y on November 1, 2020*

I have been needing these for a long time and didn't even know it. Mechanical relays fail pretty quick in some applications and have other issues. This works perfectly with a control voltage of greater than 3 volts and is dead silent. No moving parts. The back is an awesome heat sink. Easy to mount and hook up. Love these things just ordered more.
