Hint/Tip Equalizer Bars

[Sophb21]

has anyone purchased Equalizer bars as part of their home gym equipment? If so do you find you use them much?

I'm trying to decide if I need them. I've read a little bit of mixed reviews saying they weren't very stable and therefore useless.

I suppose the main reason I'm interested is to see if I can use these as a pull up alternative instead of resistant bands or a pull up bar. I'm thinking especially for P90X3.

Please tell me your thoughts and experience with these!
