I have been wearing these for 6 weeks. I am a plumber and work on my knees occasionally and wore through the rubber toe cap they put on in 4 weeks, and was through the leather in about another week. They hurt my feet a lot. I paid a bunch of extra money for the custom orthotics, and those make my feet hurt even worse.

If you are in the trades and going to be working on your knees I would go for something that has a lot more rugged toe cap.

I've seen a some guys say to just read the code book, which doesn't really work for a lot of people.

I am in Colorado trying to study for the master plumber exam. I have tried to look for study material and courses online and have found very few reviews for the material out there, and most of them negative. I'm wondering if any of you guys have used any of these materials and what you think of them before I spend a ton of money on one.

I bought the 600 question study pack from Tests.com and it has been pretty helpful, however, it does not cover isometrics, fire sprinklers, and never really gets you into the IRC codebook.

I was about to pay for the study materials from PSI, and found their free practice questions and it was just absolute AI garbage. The reviews I could find from people using it for the electrician's test and real estate and said the same things. Has anyone tried their practice exams? (I have attached a few pictures of their practice questions.)

I'm also trying to figure out what all topics are covered, I thought fuel gas was on there but a friend of mine told me that they do not test on that. Any insights would be super appreciated.
