Excellent product
I tried using mechanical relays on a refrigerator Arduino project but they created lots of electrical noise and lead to reboots. Once I replaced the mechanical relays with these relays, the Arduino sketch ran great. I needed to control 7 amps with a 12 mp surge, but I ordered the 40amp relay, just in case. It's 5 months later and they still work.

SSDs at their best.
These Solid-State relays were exactly what I was looking for. If you need some, these are as good as you will find. I highly recommend them. When I needed some, many years ago-they were like $25 apiece. Now a days they are much more reasonable. Buy them.

Know what your doing
Works ok just check ur voltage know what your doing

Resistive loads only, not inductive/capacitive
WARNING! This SSR is for 'temperature control' as in a resistive load. Do not try to run a motor or ballasted flouescent light with it.

Very low quality - clone!
The SSR quality is VERY low, the user should avoid applying a high amper(max 25% amp of the max amp).
