They don't have anything that's not in a Savarese green book. You can read Savarese in 2 days cover to cover and you'll get a LOT more info that OMGOMT skipped or considered low yield. The thing is in Comlex you get low yiled a lot more often than high yield lol, so I wouldn't use an inferior resource. Why? The only positive in OMG OMT was last year when you could watch 14 videos in like 5 hours just to refresh knowledge - useful before OMM exam.
Also, I had subscription for OMG OMT that I bought from them and guess what? They took down the website last year. Then they provided crippled version of it on youtube as a remedy. I still can't get pdf notes that I used to study on their website. Why would you do that to people who bought it? First they told us they were going out of business, then they said they are revising website. I'm just saying that they can do that kind of things without warning and leave you in void.
