Excellent!!
My heat press would exceed the set temperature. Did a bit of research and found that SSR might be the cause. Took a chance on buying this based on price vs a new press or control box. Worked perfectly!

NO GOOD _ Light turns on but doesnt connect
Had them saved for project and when tested found two ordered turn trigger lights on but dont make any AC connections, waste of money and time and return window.

Using With Arduino Mega 2560 to control 2kw Kiln at 240vac
I had some old SSRs (another brand) that wouldn't activate with 5v from the Arduino without using a mosfet at 12v. I tried the HiLetgo SSR-25DA module and am totally pleased with the performance. No problem switching with 5v data output pin from Arduino. The program was a simple test of the kiln (it was a DIY project and hasn't been used in years), just to see how long it would take to go from room temperature to 1000 F. Took less than 30 minutes. The relay felt a bit warm drawing 9 amps, so I added an aluminum heatsink to keep it running cooler.

Will not switch on air pump , updated
I bought this relay to control a VIVOHOME Electromagnetic Commercial Air Pump 32W. This relay will not turn-on the air pump. I have an other relay CG Solid State Relay SSR-25DA. This relay will turn-on the air pump. Update : Added snubber across power line for air pump and the relay started working. Subber is series RC circuit R=220, C=0.1uF

Works good as a replacement to the original part
Worked great I needed mine for a t shirt heat press

Works
I used one to replace a standard relay the controls the heater in my hot tub. I was tired of replaceing burned out relays. These work great, runs fairly cool with a heat sink drawing 18 Amps

It’s pretty simple to use , get the right DA and then plug and play simple. I’m not an electrician it works well in my heatpress.

The picture of the relay showed it to be cRUus certified, which it wasn't. I will return this unit today. Waste of time. J.

purchased 4 of these and none will work- tried on 12vdc and 24vdc both supposed to work from 3-32 vdc
