Pls don't take JP701 into consideration any more because it is out of date..... Every time when you are doing some purchases pls check in our official website to see if there are newer models for your need....... As for the MS509, sorry we don't produce it for quite a long time.... Some MS509 sold in internet are clone ones, and we could not tell which is original.. That is also why we keep on introducting new prodocts....
