I have one that came straight from China and knew what I was ordering when I ordered it. I have been pleased with, what little I have used it. Just played with it in the house and one time with my Dish 500 conversion on a warm early winter day. So, can't give a long term use report.
I have read very good reviews on this model. If you want all the bells and whistles, go with the one some members here offer. The one I have doesn't do everything you see listed, but is still a very functional meter. It does not identify the satellite, but will list what is on the transponder you are tuning to, so that you can be sure you are on the right satellite. I don't think either version identifies the satellite.
It is very easy to create and load a custom satellite list into the meter. That way you can easily update it. Pretty easy to add one just using the meter.
If you want support, buy from approved sources. Some of them are members here and will probably speak up.
