It's a real pain in the ass to do so and the result isn't even that impressive. The instructions don't help at all either, but I'd look up a video on how to transform it and do it yourself. Only then will you understand how the all joints are (and aren't) supposed to connect in MS mode. I'd say go with the RG if you really like the wave rider mode.
In mobile suit mode it's decently posable. The only consistent issue I had was were the legs connect to the waist, but once you jam it in just right it stays put. If anything, pick it up because Zeta Gundam is best Gundam.
