It works in general, but the non-standard overflow and drain is a bit of a challenge for some plumbers.  My contractor who installed it also didn't put in the mortar bed like I repeatedly asked.  Later after installation They tried to fix it by drilling holes in the wall and injecting closed cell foam.  By then it's too little too late.  The tub is still a bit bouncy and a crack appeared because of the unstable bottom.  Make sure you install it correctly or get a person who knows what they're doing.
