I absolutely love it for all the customization abilities it gives me but objectively speaking it is a big buggy - I get errors at least once a day, which compared to a stable Go launcher might seem like much. I have a SGS2 but people with phones with lower RAM have spoken of the launcher lagging at times, I haven't had any issues with that. Overall, factoring in the Beta buggyness and the steep intitial learning curve, I'd still rank this as my favorite launcher hands down, and I have tried plenty. If you want to try it I'd suggest keeping it as a secondary one for a few days until you figure out whether it works for you not.
