## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Good relays
  

*by S***T on Reviewed in the United States on November 4, 2019*

I use these all the time at work and have had no problems with them except the wire is no a large enough guage for the advertised amp rating.

### ⭐⭐⭐⭐ 







  
  
    Work well, 1.2v drop out is a little off
  

*by R***J on Reviewed in the United States on August 5, 2015*

I tested these on my adjustable bench power supply, and they do really well.The listed pick up voltage is 7.8v, they exceed this slightly and pick up at 7.5v. Really nice.The drop out voltage is listed as 1.2v and they did not quite meet the spec and would drop out right at 3v. That is a little disappointing but for my purposes this is more than adequate.The coils consume right about 100mA at 12v and it drops slightly as the voltage goes down. This is not negligible, and if you're using these on a battery powered project there will be a slight impact to battery life. But considering the price, I was more than happy.I tested these with a dummy load at 40 amps. The relay continued to function and was only slightly warm, but the wiring became too hot to touch. At 30 amps the wiring became warm but not at a level that I would worry about as the wire is rated 70c. You could easily replace the wiring with something a higher gauge if needed and probably push this relay up to 50a before catastrophic failure.

### ⭐⭐⭐⭐⭐ 







  
  
    Almost perfect
  

*by 2***O on Reviewed in the United States on April 8, 2014*

Pro's:*Very affordable*bases interlock with dovetails side to side AND front to back leaving you with plenty of mounting options.*Base mount not relay mount. This allows you to remove the relay and the socket will stay in place.*Compact. Smaller than a bosch relay but maintains the amperage capacity.Con's:*2 different size spade terminals in the relay socket.Overall well worth the money. If you plan to remove the wiring and terminals and replace them with your own you might have a hard time finding the smaller ones. I was able to find them at a hole in the wall electronics reseller after searching high and low on the internet and around town. Still this was the best and CLEANEST install option I found out there without breaking the bank.
