However, when purchasing LeTV, one year’s membership can be reduced by 300 yuan for the hardware price, which is equivalent to an annual fee of 190 yuan.

Like the clarity of the video, if you don’t manage membership, you can only enjoy the SD resolution. You can’t remove the one-minute advertisement before the movie. The popular videos that are shown in the online cinema can’t be watched in the first place. However, if the annual fee of 190 yuan is used, it is still worthwhile.
