I've tried it a few times, and like... it's frustrating because I can get so close, but the missing bit feels like an impenetrable wall. Like, I can occasionally make something, but it isn't anywhere near as nice of a model/part and it takes significantly longer to do. I tend to try it out again once every several months to see if new stuff makes it easier for me to use, but so far it hasn't been a great solution for me.
