Indeed,TS802 is a very old product,and we have been selling it for more than 10 years. The latest news is that Linsn TS802 will be discontinued in the next 2 months, and its replacement model is Linsn TS921. Definitely,TS921 is completely compatible with TS802, their difference is that TS921 has an extra function,that is,TS921 can read back configuration file of receiving card. Overall, Linsn’s products are good,especially in its quality, performance and price,but a little slow in updating. Hope that Linsn can launch more products with strong points over other similar ones!
