I have an actual MS881, the stock compression is nuts, the power crazy, build quality is top-notch, it's an awesome saw. Fire it up and a crowd gathers, and for good reason: It's a few steps beyond "sensible," which is immediately obvious.
The smurfy clone is a reasonable copy for the price, and to many people it makes sense to own a clone (politics aside). It doesn't get the same response, it's just a big saw. Recognise it needs some special consideration and it'll do the job well, including fairly big jobs.
I think in the "big picture" the long- term cost of knock-off saws is going to become more apparent, that's not something I want to get into beyond mentioning people should put some thought into their buying decisions and make intelligent choices.
