Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the performance and value of the relay. For example, they mention it works well, is good value for money and that it works great to power a 3D printer's heated bed. Opinions are mixed on quality and temperature control.
AI-generated from the text of customer reviews
Customers like the performance of the relay. They say it works perfectly, it works great to power their 3D printer's heated bed, and has no problems thus far. Some say that it turns on fine and glows dimly instead of turning off completely.

At first the FUSE was blowing every time I activated my HEATED BED. Thought it was SSR, but realized after reading about some one else having the same issue - they used an CAR FUSE and that resolved their issue.
I was using a 5x20 3Amp fuse in my PSU, this could not handle the load. So upon inquiring with an electrician about my 800 Watt load, replaced the fuse with 5x20 12Amp VIOLA!
NOW it gets nice and hot, while the SSR doesn't get hot at all (Installed a 40mm fan that isn't needed - hmm maybe it will warm up after a 3Day print job?).
I am posting a simple diagram, to help you - as I have installed and use my SSR+HEATED BED. (SWITCH -W- FUSE is used, not shown in diagram, connected to the same mains lines on PSU as BED & SSR).
LEGAL DISCLAIMER:
i take no responsibility or liability in your use and installation of your SSR. Merely posting diagram as I have installed.
YOU accept full responsibility and liability, with full knowledge 120Volts can cause serious injury and or death. USE CAUTION! Employ an electrician for installation if required.

The breaker for the water heater I have is a dual pole rated at 30 amps and the element is rated at 3500 watts so probably runs around 15 amps load which is easily handled by this relay with the heatsink I have in place.
Although this item has the CE mark from the manufacturer, which means it should meet all EU safety requirements, I would prefer if it had also been tested by an independent lab such as UL, ETL, or TÜV.
Quite impressed, given the price. Was much cheaper than replacing the whole controller after the original electromechanical relay smoked itself.
One thing to note about these solid state relays, they get HOT. Be sure to use proper cooling.
Even sitting in a 40 F cooler the heatsink attached to it gets very warm.
It would probably be fine to forgo the heatsink with loads under a couple amps (depending on voltage, of course). Running a 60 watt light bulb through it produced no noticeable heat after an hour.
Took a peak inside when I got it. Big solder coated traces between the screw terminals and the TRIAC (a BTA41). Opto-isolator and anti tracking slots between the AC and DC sides. Insulative coating on the PCB is very thin though.
I'm not an electrical engineer, but it looks to be of OK construction.
Good as much higher priced units? Nah. Good enough for me? Sure.
And that might good enough for you, too.
I didn’t get in details, but I assume it has semistor that require minimum load on the high side to open properly, that’s why my low voltage motor didn’t work.
Good price-quality value
