Near-incompressible analysis

Hello all,

I am studying some simple finite elements for 2d near-incompressible analysis. Particularly, I am interested in the MINI element. It is basically a 3-node triangle element with nodal pressure and displacement degree of freedoms enriched by a bubble function. Could someone that has some experience with these elements point me out about advantages and drawbacks of using these type of elements?
