## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect and much cheaper than when bought in a kit
*by M***Y on May 9, 2019*

Works perfectly for the electrical panel board at my job site. Still works like a charm.Purchased this for work and did not want to spend ridiculous amounts of cash for a Lock/out Tag/out kit.So purchased the items seperately and it was much cheaper and only purchased what I needed. No Waste!

### ⭐⭐⭐⭐⭐ Fantastic! Definitely recommend!!
*by M***L on March 13, 2019*

I wasted $99 at Home Depot for some crappy lockout kit that barely works well, especially doesn't work for locking out more than 1 of any type of breaker.HOWEVER these lockouts are fantastic! Very solidly built, and very effective! I love that I can buy as many individual pieces as I want, rather than having to buy a whole kit! They also work really well on light switches. I definitely recommend these.

### ⭐⭐⭐⭐⭐ Cannot be too safe
*by A***. on May 23, 2021*

I use LOTO (lock out tag out) at work and realized that I really needed something at home for when I'm doing electrical work, I wouldn't expect someone to reset the breaker but you never know. I haven't used this yet but did try fitting it to my household breaker and it worked flawlessly. Once closed I tried pulling on the lock and just couldn't get it off. A lock should easily fit amd work with this, just make sure to use a lock that either you have all keys for or only you know the combo to.I will say though that with this on the breaker the breaker door cannot fully close but this was to be expected.I know this can be very handy someday if my son just won't listen I can shut electricity off to his room (or at least that is what I would have liked to do to my brother growing up at times, haha).
