As we all know,Lonsdor Menus are divided into two parts: Free Menus and Subscribed Menus
1.Free menus are free use for lifetime.
2.Subscribed menus can be used for free for 180 days. You need to pay for them after the trial period
For the first six months,both K518ISE and K518S can use all menus.Their functions are same.
The difference is after the sixth month:
The free menus of K518ISE is more than K518S,so the price of K518S is cheaper than K518ISE.
The update subscription cost for K518ISE is same for every year---630USD.
You can only pay for every year.
The update subscription cost for K518S is not same.Update subscription declines year by year.
-First Year Update Subscription for Lonsdor K518S Full Functions---800USD
-Second Year Update Subscription for Lonsdor K518S Full Functions---600USD
-Third Year Update Subscription for Lonsdor K518S Full Functions---300USD
Or if you want to update for one time,you can choose Lifetime update subscription.No need pay more in the future.
-Lifetime Update Subscription for Lonsdor K518S Full Functions---3100USD
The most important difference is:
For K518ISE,you can still use subscribed functions when you get during warranty,which means you only need to pay new functions next time.
But for K518S,after out of warranty,you can't use all subscribed menus,only free menus availble.You need to pay for subscribed menus each time.
