Very Easy to Install and Worth the Price
I was very hesitant to attempt to install a replacement breaker, but two electricians wanted to charge me to replace my breaker box. My breaker box was fine, I just needed to replace one older Murray 15amp breaker. I took a photo and called the seller and relayed the information on my breaker. he assured me that the circuit breaker that I needed to replace was the circuit breaker in the description. The breaker arrived sooner that anticipated. I was not sure of how to install it, but after a few YouTube how to replace videos, I was confident that I could replace it. It literally took less than five minutes to replace and it worked! I highly recommend this Seller.

Easiest Electrical Repair
This breaker was a perfect fit for a 42 year old failed Murray breaker. It took me longer to find a place to set the box cover plate screws where they would not get lost than it took me to remove the old breaker and install this one.

Murray MP120 20-amp circuit breaker needs quality control
The price was excellent but I removed 1 star because one of the breakers had a screw that I couldn't tighten. It was never tapped out properly. I tapped it out with a 1/4-28 tap and it was fine. If I didn't have that exact tap, I couldn't have used the breaker.

Murray Breakers
Ordered these to change the breakers in my house. Because this brand was so old and the only store in my area selling them has terrible hours I took the chance to buy them online. The product came in on-time, if not a little early. They were packaged with a lot of protection for the breakers and everything was in order/correct. Very happy with the quality and punctually! Put them in about two weeks ago and having no problems.

Great replacment and good price
If you have seimens or murray breaker panel, this is the mp series and is the exact replacement you need. I had a 15 amp breaker that kept tripping. Problem solved as soon as I put in the new breaker. I would recommend buying several breakers in different amperage levels so you have backups ready to go when needed.
